BIMCamel compared to 13 other BIM tools

An honest comparison of BIMCamel against the tools people actually weigh it against: Solibri, BIMcollab (Zoom + Nexus), Autodesk Navisworks, BIM Vision, usBIM, Trimble Connect, Revizto, Dalux BIM Viewer, Autodesk Viewer, buildingSMART IFC Validation Service, Bonsai (formerly BlenderBIM), Speckle, Autodesk Revit. Every entry covers the same four things: where the two tools overlap, where they differ with both sides stated, when to pick BIMCamel, and when to pick the other one.

Facts checked 2026-08-07 — every entry carries its own retrieval date and links to the vendor page it was read from. We make BIMCamel, so we have a stake in this; that is exactly why the sources are printed rather than summarised.

At a glance

A table this size flattens real differences — two ticks are rarely the same depth of feature. The sections below carry the detail.

BIMCamel vs Solibri

Desktop rule-based model checker · Solibri (Nemetschek Group) · runs on Windows / macOS desktop · checked 2026-08-07

The reference product for rule-based model checking, and the one most client BIM requirements name by name. Solibri runs a library of parametric rules over a federated model and produces a structured, presentable QA result — that library, refined over two decades, is the thing you are actually buying. The free viewer that introduced most people to it, Solibri Anywhere, is now a legacy product being retired.

Free tier: Solibri Anywhere — legacy since 13 April 2026, free entitlement gone from v26.4.0, discontinuation planned Q4 2026. Paid from: Starter €99/year, named licence.

Where they overlap

• Checking a federated model against rules and producing a findings list a coordinator can work through.
• Clash detection between disciplines, with results grouped rather than dumped.
• Viewing and inspecting IFC — spatial tree, properties, sectioning, measurement.
• Issuing findings as BCF so they land in whatever tool the modeller uses.

Where they differ

Where it runs

BIMCamel: In the browser on any OS. Nothing to install, no account needed to start, and a reviewer joins a coordination room from a link on whatever machine they have.

Solibri: A Windows or macOS install with a named licence per seat; everyone who needs to open a result needs the software.

What a check costs

BIMCamel: IDS validation, the 19-check health and clash suite, and the full findings report all run on the free tier, with results on screen rather than behind a preview limit.

Solibri: Paid from the first serious check — Starter is €99/year and the checking tiers run to €2,772/year — and the free Anywhere viewer is legacy, with discontinuation planned for Q4 2026.

How rules are expressed

BIMCamel: buildingSMART IDS specifications, authored in the browser with the IDS maker and re-runnable against every revision, plus a fixed library of health, clearance and egress checks.

Solibri: Parametric rulesets with two decades of refinement behind them, which you can author, version and hand to a client as a deliverable.

Repeating the work

BIMCamel: Chain clean → validate → clash → export into a saved pipeline and run it over a whole folder of revisions unattended.

Solibri: Automation is available through token packages on the paid tiers.

Model size and privacy

BIMCamel: Uploads up to 500 MB on Pro and up to 1 GB on Team; files auto-delete and are never used to train AI, but they do leave your machine.

Solibri: Bounded by your workstation rather than an upload cap, and the model never leaves the building.

Pick BIMCamel when…

• You need to validate, clash-check and hand off an IFC today, without a licence or an install standing between you and the job.
• The people who need to see the result — a client, an engineer, a subcontractor — will not install desktop software to look at one model.
• The same check runs every revision, and you would rather save it as a pipeline than repeat it by hand.
• You work on macOS, Linux or a tablet, or you simply do not want another Windows seat on the budget.

Pick Solibri when…

• Your BIM Execution Plan names Solibri rulesets — no browser tool satisfies a contract that specifies a product by name.
• You need to author parametric rules and distribute them as a deliverable; IDS covers requirement checking, not Solibri's rule authoring.
• The models are too large to upload, or client policy forbids putting them on someone else's server.
• You need information takeoff and classification checking to Solibri's depth.

BIMCamel vs BIMcollab (Zoom + Nexus)

Desktop model checker + cloud BCF issue platform · BIMcollab (formerly KUBUS) · runs on Windows / macOS desktop (Zoom) + cloud (Nexus) · checked 2026-08-07

Two products that work as one: Zoom is a fast desktop IFC checker and viewer, Nexus is the cloud issue platform behind it. BCF issue management is what BIMcollab has always been best at, and the free Zoom viewer is one of the better free viewers on any desktop.

Free tier: BIMcollab Zoom free viewer — viewing, clipping, measuring, local Smart Views, point clouds. Paid from: Full platform from €12.50 per user/month billed annually (€19 monthly).

Where they overlap

• BCF 2.1 issues as the unit of coordination — raise, assign, track, round-trip.
• IFC viewing with clipping, measuring and property inspection.
• IDS-based property validation and rule-driven clash detection.
• Cloud-side issue state that several people work against, rather than a file passed around.

Where they differ

Where it runs

BIMCamel: Entirely in the browser, including the checking. A coordination room opens from a link and a guest needs no account to join it.

BIMcollab (Zoom + Nexus): Zoom is a Windows or macOS install; Nexus is the cloud half. The checking lives on the desktop side.

What a check costs

BIMCamel: Rule-based clash detection, IDS property validation and every export run free, at every tier.

BIMcollab (Zoom + Nexus): The free Zoom viewer covers viewing, clipping, measuring, local Smart Views and point clouds; rule-based clash, IDS validation, batch Smart Issues, lists and Excel/CSV export are the paid Zoom edition.

Reaching the modeller

BIMCamel: Standards-based BCF 2.1 round-trip, so issues land in any BCF-compatible tool — but nothing runs inside Revit, Archicad or Tekla.

BIMcollab (Zoom + Nexus): Plug-ins for Revit, Archicad and Tekla put the issue in front of the modeller inside the application they are already in.

How you pay

BIMCamel: Free at every tier for every tool; Pro €19/month and Team €49/month raise caps and add team features rather than unlocking capability.

BIMcollab (Zoom + Nexus): Per user per month on the full platform, from €12.50 billed annually.

Repeating the work

BIMCamel: Saved pipelines run a chain of tools across a folder of models on their own.

BIMcollab (Zoom + Nexus): Batch generation and updating of Smart Issues, on the paid edition.

Pick BIMCamel when…

• You want the checks — IDS, clash, model health — without buying the tier that unlocks them.
• The reviewers you need are external and will not install a desktop viewer to take part.
• You want the whole loop in one browser tab: open the model, check it, raise the issues, share the room.
• The same review happens every revision and you would rather automate it than repeat it.

Pick BIMcollab (Zoom + Nexus) when…

• Issue management is the centre of your process and your modellers live in Revit, Archicad or Tekla — the plug-in round-trip is genuinely good and we have no equivalent inside those applications.
• You want Smart Views: saved, shareable colour-and-filter rules that make a federated model readable at a glance.
• You need the checker to run offline on your own hardware, with model size bounded by the machine rather than an upload cap.

BIMCamel vs Autodesk Navisworks

Desktop coordination, clash and 4D · Autodesk · runs on Windows desktop · checked 2026-08-07

The incumbent coordination tool on Autodesk projects: aggregate everything into an NWD, run Clash Detective, drive the 4D schedule from TimeLiner, and quantify from the same aggregated model. It reads a very wide list of native formats, which is exactly the thing an IFC-first tool cannot match.

Free tier: Navisworks Freedom — free viewer for NWD and DWF only. Paid from: Autodesk's overview page did not render list prices when we read it — check their buy page.

Where they overlap

• Federating several discipline models into one coordination model.
• Clash detection between those disciplines, with grouped, reviewable results.
• Navigating and interrogating the federated model — tree, properties, sections, measurement.
• Getting coordination findings out to the people who have to fix them.

Where they differ

What it reads

BIMCamel: IFC2x3, IFC4 and IFC4x3 — the openBIM exchange every authoring tool writes — and we publish a free, MIT-licensed Navisworks plug-in so NWD, NWF and NWC models can come across as IFC.

Autodesk Navisworks: Native aggregation of RVT, DWG, NWC, point clouds and dozens of other formats, with no IFC export step in between.

Where it runs

BIMCamel: Any browser, any OS, no install; anyone you send a link to can look at the model and comment on it.

Autodesk Navisworks: Windows only, per seat. Freedom, the free viewer, opens NWD and DWF — but not IFC, so it does not help a partner who was sent one.

Requirement checking

BIMCamel: buildingSMART IDS validation, plus model health, clearance and fire-egress checks, all free and all re-runnable per revision.

Autodesk Navisworks: No IDS engine — checking against an Information Delivery Specification is not something Navisworks does.

Schedule and quantities

BIMCamel: Quantity takeoff and data extraction to Excel, COBie and BCF; no 4D scheduling.

Autodesk Navisworks: TimeLiner 4D scheduling and quantification against the aggregated model, which is a large part of why teams buy it.

What it costs to start

BIMCamel: Free, including clash detection, with no account needed to try it; Pro is €149/year.

Autodesk Navisworks: A paid subscription for Manage or Simulate; Autodesk's product overview did not render a list price when we read it, so budgeting means asking them.

Pick BIMCamel when…

• The models you are handed are IFC, and you want to check, clean and coordinate them without a Windows workstation.
• You need clash detection today and cannot wait on a licence — it is free here, with the full report on screen.
• People outside your firm have to see the result, and they will not install anything.
• You want NWD data out of the Autodesk world entirely: our free exporter plug-in writes IFC 2x3 or IFC4 with properties and hierarchy intact.

Pick Autodesk Navisworks when…

• The project is native Autodesk end to end and lives in Revit, DWG and NWC — aggregating without an IFC round-trip is worth a lot.
• You need TimeLiner 4D scheduling or quantification against the aggregated model.
• The federated model is enormous and needs workstation hardware rather than an upload.
• Your issues already flow through Autodesk Construction Cloud.

BIMCamel vs BIM Vision

Free desktop IFC viewer with a plug-in store · Datacomp · runs on Windows desktop · checked 2026-08-07

A genuinely free Windows IFC viewer — no account, no trial timer, free for commercial use — that reads IFC 2x3 and IFC4 exported from Revit, Archicad, Tekla, Vectorworks, Allplan, BricsCAD and others. Extra capability comes from a plug-in interface, and the plug-ins are where the money is.

Free tier: The whole viewer — "free for personal and commercial use". Paid from: Free; individual plug-ins sold separately in the plug-in store.

Where they overlap

• Opening an IFC and exploring it: spatial tree, element properties, sections, measurement.
• Reading models exported from every major authoring tool, at no cost.
• Comparing revisions and inspecting what changed between them.

Where they differ

Where it runs

BIMCamel: Any browser on any OS — macOS, Linux, ChromeOS and tablets included — and a model can be shared as a link rather than a file.

BIM Vision: Windows only, installed locally.

What comes with it

BIMCamel: 40+ tools alongside the viewer: IDS validation, clash detection, model health, cleanup and repair, merge and split, conversion to glTF, OBJ, STEP, COBie, DXF and Excel — all included, all free.

BIM Vision: The viewer is complete and free; clash, BCF workflows and other extras are bought individually from the plug-in store.

Working with other people

BIMCamel: Coordination rooms with live presence, 3D pins, viewpoints and BCF 2.1 round-trip, joinable by link with no account.

BIM Vision: A single-user desktop tool — collaboration means sending the file.

Where the model sits

BIMCamel: Uploaded and processed on our servers; files auto-delete after their retention window and are never used to train AI.

BIM Vision: Nothing leaves the machine, which settles it for any firm whose policy forbids uploading client models.

Repeating the work

BIMCamel: Saved pipelines chain tools and run over a whole folder of models unattended.

BIM Vision: One file, one person, one machine — there is no batch mode.

Pick BIMCamel when…

• Viewing is the start of the job, not the end of it: you also need to validate, clean, convert or split the model.
• You are not on Windows, or you want the model open on a tablet in a meeting.
• Somebody else needs to see it, and a link beats emailing a 300 MB file.
• The same processing happens on every revision and should run itself.

Pick BIM Vision when…

• You want a fast, free offline viewer on Windows and nothing more — it is very good at exactly that.
• Uploading client models is not an option, on policy or contract grounds.
• You work on site or on a laptop with no reliable connection.

BIMCamel vs usBIM

Cloud BIM platform with a free browser viewer · ACCA software · runs on Browser (usBIM.browser) + Windows desktop apps · checked 2026-08-07

ACCA's answer to the same question BIMCamel asks: put BIM in the browser. The free account is unusually generous — 10 GB of cloud storage and a list of free apps including the viewer, federation, BCF, chat and meetings — and the platform extends into ACCA's paid authoring and estimating products.

Free tier: usBIM.browser and a set of free apps, with 10 GB cloud storage on a free account. Paid from: Free tier; other usBIM apps are bought individually.

Where they overlap

• Browser-native IFC viewing with no install, on any device.
• Federating several models and reviewing them together.
• BCF issue tracking as part of the free offering.
• A cloud home for models that a team can work against.

Where they differ

Getting started

BIMCamel: Every tool runs as a guest: open the sample building or drop your own IFC and go, with no signup at all.

usBIM: An account comes first — free, but required before anything happens.

How capability is packaged

BIMCamel: One product with 40+ tools included. No plan unlocks a tool the free tier does not already have; paid tiers raise caps and add team features.

usBIM: A catalogue of apps. The free set is real and broad — viewer, federation, BCF, chat, meetings, GIS — and validation and checking generally mean buying more apps.

Storage and retention

BIMCamel: Short retention by design — guest uploads delete when the download finishes, free accounts keep 7 days, Pro and Team keep results until you delete them.

usBIM: 10 GB of persistent cloud storage on the free account, which is more generous than anything we offer for free.

Repeating the work

BIMCamel: Saved pipelines chain any tools together and run across a folder of revisions.

usBIM: No equivalent pipeline automation.

Pick BIMCamel when…

• You want to run a tool right now without creating an account first.
• You need validation and clash included rather than assembled from separately-bought apps.
• The work repeats every revision and should be a saved pipeline.
• You want the checks and the coordination room in the same place as the file processing.

Pick usBIM when…

• You want a free cloud home for models with real, persistent storage — 10 GB on the free tier is a genuinely good offer.
• The breadth of the free app set matters: document management, GIS, point clouds and meetings in one account.
• You already work in ACCA's authoring, structural or estimating software and want the continuity.

BIMCamel vs Trimble Connect

Common data environment with 2D/3D viewers · Trimble · runs on Browser, desktop and mobile · checked 2026-08-07

A CDE first and a viewer second: files, folders, versions, permissions and ToDos for a whole project, with 2D and 3D viewers on top and deep ties into Tekla and SketchUp. It is the category BIMCamel is not in — BIMCamel processes models, Connect governs them.

Free tier: The pricing page we read listed only a 30-day $0 trial — check whether a permanent free tier still exists. Paid from: Pro $149 per user/year (10 GB); Innovate $349 per user/year (20 GB).

Where they overlap

• Browser-based 3D model review that a distributed team can share.
• BCF issues moving between the review tool and the authoring tool.
• A place models live that is not somebody's laptop.
• Mobile access to the model for people who are not at a desk.

Where they differ

What the product is for

BIMCamel: Doing things to models: validate, clash-check, clean, repair, convert, merge, split, extract — 40+ operations, chainable into pipelines.

Trimble Connect: Governing project information: file structures, versions, permissions, approvals and an audit trail across the whole team.

Requirement checking

BIMCamel: buildingSMART IDS validation and a 19-check health, clash, clearance and egress suite, free.

Trimble Connect: No IDS validation and no rule-based checking engine; it is a data environment, not a checker.

How you pay

BIMCamel: Free for every tool, including for occasional reviewers, who need no account at all to join a room.

Trimble Connect: Per named user per year — Pro $149, Innovate $349 — so occasional reviewers cost money. The pricing page we read showed a 30-day trial rather than a permanent free plan.

Authoring-tool ties

BIMCamel: Openly IFC and BCF; a free Navisworks exporter plug-in, and nothing that depends on a particular authoring vendor.

Trimble Connect: Tekla and SketchUp integration that nothing browser-native matches.

Pick BIMCamel when…

• The job is to check or fix a model, not to file it — validation, clash, cleanup and conversion are the product here.
• You need people to review something without buying them a seat.
• You want the processing to repeat itself across revisions as a saved pipeline.
• You want to try it before anyone signs anything.

Pick Trimble Connect when…

• You need a real CDE: controlled files, versions, permissions and an audit trail for a whole project team.
• Field and mobile use across a large site team is central to how you work.
• You are a Tekla or SketchUp shop and want the integration.

BIMCamel vs Revizto

Enterprise issue tracking and coordination · Revizto · runs on Desktop, browser and mobile clients · checked 2026-08-07

Coordination-meeting software: 2D sheets and 3D models in one synchronised environment with an issue tracker built for large teams running weekly clash sessions across disciplines. It is bought by organisations, not by individuals.

Free tier: None published. Paid from: Not published — quote only.

Where they overlap

• Running a coordination review over a federated model and tracking what comes out of it.
• Clash detection feeding an issue list rather than a static report.
• Issues that move between the review tool and the people who fix them.
• Model review from a browser or a phone as well as a desktop.

Where they differ

Who it is built for

BIMCamel: Solo coordinators, small studios and students — the free tier is the product, and one person can get the whole job done in an afternoon.

Revizto: Enterprises running multi-discipline coordination at scale, with the issue tracker as the organisation's system of record.

What it costs

BIMCamel: Published and flat: free, Pro €19/month, Team €49/month. You can see the price before you talk to anyone.

Revizto: No published list price and no free tier — pricing is by quote. Third-party sites circulate figures; we are not repeating them because we could not verify them at the source.

2D alongside 3D

BIMCamel: 3D model work, plus 2D output — plans and sections exported to DXF or SVG. There is no synchronised 2D sheet environment.

Revizto: 2D sheets and 3D models kept in sync, which matters when the argument in the room is about a drawing.

Requirement checking

BIMCamel: IDS validation and model health checks alongside the clash engine, so "is this model correct?" and "do these clash?" are the same session.

Revizto: Clash and issue tracking; no IDS validation engine.

Pick BIMCamel when…

• You are one person or a small team, and an enterprise coordination platform is more product than the job needs.
• You want to know the price without a sales call, and to start without one.
• Model checking — IDS, health, clash — is the work, not just issue administration.
• The people you coordinate with change from project to project and cannot be licensed in advance.

Pick Revizto when…

• You are running coordination for a large multi-discipline project and need an issue tracker the whole organisation lives in.
• Weekly coordination meetings across 2D and 3D are the rhythm of the project.
• You need live sync from authoring tools so the coordination model is never stale.

BIMCamel vs Dalux BIM Viewer

Free BIM viewer inside a construction platform · Dalux · runs on Desktop and mobile, with authoring-tool plug-ins · checked 2026-08-07

A free viewer that is the front door to a much larger construction platform. Its distinguishing trait is field use: very large models stream to a phone on site well, and the free viewer ships plug-ins for the major authoring tools.

Free tier: The BIM Viewer itself is free, including plug-ins to Revit, Navisworks, Tekla and Archicad. Paid from: Paid modules (Box, Field, FM, Handover) are quote-only.

Where they overlap

• Free model viewing with nothing to pay and no licence key.
• Getting a model in front of someone who is not at a workstation.
• Sharing a model with people outside the team that produced it.

Where they differ

What the tool does

BIMCamel: A working toolkit: IDS validation, clash detection, model health, cleanup, repair, merge, split and conversion, plus the viewer.

Dalux BIM Viewer: Viewing, well, on hardware that struggles elsewhere. There is no checking engine — no IDS, no clash.

On site

BIMCamel: Runs in a mobile browser, but it is built for the desk: processing models, not walking a floor with them.

Dalux BIM Viewer: Field use is the point — large models stream to a phone on site, which is where Dalux earns its place.

What growing into it costs

BIMCamel: Published: free, Pro €19/month, Team €49/month, and every tool is in the free tier.

Dalux BIM Viewer: The viewer is free; everything past it — Box, Field, FM, Handover — is quote-only, so the cost of growing into the platform is not knowable up front.

Repeating the work

BIMCamel: Saved pipelines run a chain of operations over a folder of models unattended.

Dalux BIM Viewer: No batch or pipeline automation.

Pick BIMCamel when…

• You need to check or change the model, not only look at it.
• IDS validation or clash detection is part of the job.
• You want to know what the paid tiers cost before you commit to a platform.
• The processing repeats every revision and should be automated.

Pick Dalux BIM Viewer when…

• Getting models into the hands of people on site, on their own phones, is the priority.
• You want a free viewer with direct plug-ins to Revit, Navisworks, Tekla and Archicad.
• You expect to grow into document control, field forms or handover on one platform.

BIMCamel vs Autodesk Viewer

Free online file viewer · Autodesk · runs on Browser (WebGL) · checked 2026-08-07

A free browser viewer that opens an unusually wide list of formats — Autodesk cites over 80, including DWG, RVT, STEP and SolidWorks — with measuring, markup and sharing. If your problem is "I was sent a file and cannot open it", this is often the shortest path.

Free tier: The viewer is free. Paid from: Free.

Where they overlap

• Opening a model in a browser with nothing installed.
• Measuring and marking up what you find.
• Sharing what you are looking at with someone else.

Where they differ

What it reads

BIMCamel: IFC2x3, IFC4 and IFC4x3, deeply — every tool understands the schema, not just the geometry.

Autodesk Viewer: Over 80 formats including native RVT, DWG and STEP, which an IFC-first tool will never match.

What you can do with the file

BIMCamel: Validate against IDS, detect clashes, audit model health, edit property sets, repair GUIDs, fix coordinates, merge, split and convert to glTF, OBJ, STEP, COBie, DXF or Excel.

Autodesk Viewer: View, measure, mark up and share. Nothing changes the file and nothing checks it.

Coordination

BIMCamel: BCF 2.1 rooms with live presence, 3D pins and viewpoints, joinable by link.

Autodesk Viewer: Markup and sharing, but no BCF issue workflow.

File ceiling

BIMCamel: Up to 25 MB as a guest, up to 100 MB on a free account, up to 1 GB on Team.

Autodesk Viewer: A published ceiling of 1 GB per file, higher than our free tiers allow. The pages we read did not state whether a sign-in is required to upload.

Pick BIMCamel when…

• The file is IFC and you need to do something to it — check it, clean it, convert it, split it.
• You need a validation or clash result, not just a look at the geometry.
• The review needs issues attached to it that survive the meeting.

Pick Autodesk Viewer when…

• You need to open a non-IFC file once — an RVT, a DWG, a STEP — and nothing else.
• The file is close to a gigabyte and you only need to see it.

BIMCamel vs buildingSMART IFC Validation Service

Official IFC conformance validator · buildingSMART International · runs on Browser · checked 2026-08-07

The authoritative answer to one narrow question: is this file valid IFC? It runs normative checks — STEP physical file syntax, the IFC schema including the formal propositions encoded in EXPRESS, and the normative IFC rules — plus non-normative industry-practice and bSDD compliance checks. Free, with a login, for non-zipped .ifc files up to 256 MB.

Free tier: Free, with an account. Paid from: Free.

Where they overlap

• Telling you whether an IFC file is sound before you pass it on.
• Free, browser-based checking with nothing to install.
• Catching problems that would otherwise surface in someone else's software.

Where they differ

What "valid" means

BIMCamel: Fit for the project: does the model carry the properties, classifications and structure the brief asked for, and does it hold together geometrically? IDS specs, model health, clash, clearance and egress.

buildingSMART IFC Validation Service: Conformant to the standard: STEP syntax, the IFC schema including EXPRESS propositions, the normative IFC rules, and bSDD compliance — the reference implementation of that question.

What happens after the verdict

BIMCamel: Fix it in the same session — repair GUIDs, correct coordinates, edit property sets, purge orphans, then re-run the check and export the result.

buildingSMART IFC Validation Service: A verdict and a report. Repair happens elsewhere.

Scope and limits

BIMCamel: 40+ tools, models to 1 GB on Team, no account needed to start, and results exportable as BCF, HTML, CSV or XLSX.

buildingSMART IFC Validation Service: Deliberately narrow: one file at a time, .ifc only, no zip, 256 MB, account required. No viewer, no clash, no BCF.

Pick BIMCamel when…

• The question is whether the model meets the project's requirements, not just the schema's.
• You need to fix what the check found, not only learn that it is there.
• You want the result as BCF or a report someone else can act on.

Pick buildingSMART IFC Validation Service when…

• You need an authoritative conformance verdict — to settle an argument with a software vendor, or to prove an export is standards-compliant.
• You need schema-level depth, including the EXPRESS rules general-purpose tools do not implement.
• Honestly: use it alongside BIMCamel rather than instead of us. We are not a substitute for the official validator.

BIMCamel vs Bonsai (formerly BlenderBIM)

Free, open-source native IFC authoring · IfcOpenShell community · runs on Blender on Windows, macOS and Linux · checked 2026-08-07

A Blender add-on that authors and edits IFC natively — no proprietary format in the middle — built on IfcOpenShell, the library a large share of the openBIM world runs on. Free, open source, and the most capable free openBIM tool that exists, if you are willing to learn Blender.

Free tier: All of it — free and open source. Paid from: Free.

Where they overlap

• Working on IFC directly, as the native format rather than an export.
• IDS validation against a buildingSMART specification.
• BCF issues in and out.
• Free at the point of use, with no licence key and no trial timer.

Where they differ

How you get to it

BIMCamel: Open a browser tab, drop the file, and the tool is running — the sample building is already loaded if you have nothing to hand.

Bonsai (formerly BlenderBIM): Install Blender, install the add-on, and learn both. The ceiling is far higher and the first hour is far steeper.

Authoring

BIMCamel: We do not author. Geometry comes in as IFC and leaves as IFC; there is no modelling, no families, no parametric editing.

Bonsai (formerly BlenderBIM): Full native IFC authoring — modelling, drawings, scheduling, costing and analysis, all writing real IFC.

Working with other people

BIMCamel: Hosted coordination rooms with presence, pins and viewpoints, joinable from a link by someone with no account and no software.

Bonsai (formerly BlenderBIM): A local desktop tool; collaboration is whatever you build around it with files and version control.

Automation

BIMCamel: Saved pipelines: chain tools in a UI and run them over a folder, no code.

Bonsai (formerly BlenderBIM): The whole IFC model is scriptable in Python, which is more powerful and asks more of you.

Pick BIMCamel when…

• You want the job done in the next ten minutes without installing or learning anything.
• Somebody outside your team has to see the model or take part in the review.
• You want the repeatable workflow without writing code.

Pick Bonsai (formerly BlenderBIM) when…

• You need to author or deeply edit IFC — that is a different product category and Bonsai does it for free.
• You work on Linux, which almost nothing else in this table supports.
• You want to script model operations yourself, or you need everything to stay on your machine.
• Plainly: it is excellent, and we recommend it without reservation.

BIMCamel vs Speckle

Open data platform for AEC · Speckle Systems · runs on Browser + connectors in authoring tools · checked 2026-08-07

Not a checker and not a viewer — a data platform. Connectors push geometry and data out of Revit, Rhino, Grasshopper and others into a versioned stream you can diff, dashboard and automate against. It solves interoperability, where BIMCamel solves what to do with the IFC once you have it.

Free tier: Explore plan — 1 project, up to 10 users, 30-day version history. Paid from: Team $99/month.

Where they overlap

• Browser-based review of model data with nothing installed.
• Seeing what changed between two versions of a model.
• Automating work over models instead of doing it by hand.
• A free tier that is a real tier rather than a countdown.

Where they differ

What moves between tools

BIMCamel: IFC files — the openBIM exchange, read and written by everything, with no connector to install anywhere.

Speckle: Structured object streams via connectors installed in each authoring tool, avoiding the IFC round-trip entirely.

Checking the model

BIMCamel: IDS validation, model health auditing, clash, clearance and egress checks — the reason most people arrive.

Speckle: Basic validation only; no IDS, no clash detection, no health auditing.

Version history

BIMCamel: Revision comparison between two IFC files, showing added, removed, moved and modified elements by GlobalId.

Speckle: Granular, object-level version history and diffing across authoring tools, which no file-based workflow matches.

What the free tier holds

BIMCamel: Every tool, unlimited projects, no project count at all — the caps are file size and runs per day.

Speckle: One project and 30 days of version history on the free Explore plan; $99/month for Team.

Pick BIMCamel when…

• The model needs checking, cleaning or converting — that is the job here.
• You want to work on the IFC you were sent, without installing connectors in anyone's authoring tool.
• Coordination issues need to come out as BCF.
• You have more than one project and do not want to pay $99/month for the second.

Pick Speckle when…

• Your problem is moving structured data between design tools and versioning it, not validating an IFC.
• You want object-level diffs and dashboards over live model data.
• You are building on top of a platform and want the API, SDKs and automations.

BIMCamel vs Autodesk Revit

BIM authoring (a different category — listed because people ask) · Autodesk · runs on Windows desktop · checked 2026-08-07

Revit is where models are made. BIMCamel is not an alternative to it and has never claimed to be — we cannot author a wall. This card exists because "BIMCamel vs Revit" is a search people run, and the honest answer is that they do different jobs: Revit authors, BIMCamel checks, cleans, converts and shares what Revit exports.

Free tier: Trial and education licences only. Paid from: $3,005 per year, or $380 per month, for one user.

Where they overlap

• Very little, honestly — this is a sequence, not a choice. Revit produces the IFC; BIMCamel is what happens to it next.
• Both read and write IFC, and both can inspect a model's properties and quantities.
• Both automate repetitive work — Dynamo inside the model, pipelines over the exported file.

Where they differ

What it is for

BIMCamel: Everything after the export: validating against IDS, auditing health, detecting clashes, cleaning and repairing, converting, coordinating and sharing.

Autodesk Revit: Authoring: modelling, families, documentation, sheets, schedules and revisions.

Who needs a licence

BIMCamel: Nobody. Reviewers, clients and subcontractors open a link; the tools run free with no account.

Autodesk Revit: $3,005 per year or $380 per month per user, Windows only — and everyone who needs to open the model needs the software.

Checking the export

BIMCamel: IDS validation and health auditing on the IFC Revit produces, so an export defect is caught before the recipient finds it.

Autodesk Revit: An interference check inside the model; no IDS validation of the exported file.

Pick BIMCamel when…

• The model already exists and you need to check, clean, convert or share what came out of it.
• You want to verify an IFC export before sending it, rather than after a client rejects it.
• The people who need to see the model do not have — and should not need — an authoring licence.

Pick Autodesk Revit when…

• You need to author a model. Nothing here substitutes for that.
• Then bring the IFC it exports back to BIMCamel for validation, cleanup, conversion and sharing.

Where BIMCamel loses

Six things the products above do that BIMCamel does not. If one of these is your job, buy the tool that does it.

We do not author models

There is no modelling in BIMCamel: no walls, no families, no parametric editing. Geometry comes in as IFC and goes out as IFC. If you need to create or redesign a model, that is Revit, Archicad, Tekla or Bonsai — and Bonsai does it for free.

We are not a CDE

No document control, no permission matrices, no ISO 19650 approval workflows, no revision registers. The workspace holds your models and results; it does not govern a project's information. Trimble Connect, Dalux and BIMcollab's platform are built for that and we are not.

IFC first, and mostly IFC only

We read IFC2x3, IFC4 and IFC4x3. Not RVT, not NWD, not DWG. Our free Navisworks plug-in exists to get NWD data out to IFC, but if your project never leaves native formats, Navisworks and Autodesk Viewer will serve you better.

Upload caps, and the model has to leave your machine

Guests get up to 25 MB and 3 runs / day; a free account gets up to 100 MB and 6 runs / day; Pro reaches up to 500 MB, Team up to 1 GB. A desktop viewer has no such ceiling. And processing happens on our servers — files auto-delete and are never used to train AI, but if your client contract forbids uploading models anywhere, use BIM Vision or Bonsai instead.

No rule authoring, and no name recognition

Our validation is IDS-based plus a fixed library of health and clash checks. You cannot author a parametric ruleset the way you can in Solibri, and no BIM Execution Plan names BIMCamel yet. If your deliverable is "a Solibri report", we do not produce one.

Young, and small

One engineer builds this. That means fast fixes and a public changelog, but also no 24/7 support desk, no procurement paperwork, and a shorter track record than every other product on this page. Clash detection and 3D export are also not yet verified on IFC4x3, though viewing, validation, health reports and property editing are.

Questions about this page

Is this comparison biased?

We make BIMCamel, so of course we have a stake in it. What we can do is show our work: every figure on this page carries the date we pulled it and a link to the vendor's own page, every card ends with real reasons to pick the other tool, and there is a section listing what BIMCamel is genuinely bad at. Read those first, then check the sources yourself.

How current is the pricing on this page?

Every entry shows the date its facts were retrieved — the table was last verified end to end on 2026-08-07. Vendor pricing changes without notice, tiers get renamed, and free plans get withdrawn. Treat these numbers as a starting point and confirm on the vendor's site before you buy anything.

Found something wrong here?

Tell us and we will fix it. Mail [email protected] with the claim and a link, including if you work for one of the vendors listed — a correction from the vendor is the best source there is, and we would rather be accurate than flattering.

Is BIMCamel a replacement for Solibri?

For a lot of everyday checking, yes — IDS validation, model health, clash detection and BCF issue rounds all run free in the browser, and Solibri's free viewer is being retired at the end of 2026. For parametric rule authoring and for deliverables that specifically name Solibri rulesets, no. Those are different products and we would rather say so.

Do I need to install anything or create an account to try BIMCamel?

Neither. Every tool runs as a guest in the browser — up to 25 MB per file and 3 runs / day, no signup. A free account raises that to up to 100 MB and 6 runs / day and keeps your job history. No plan unlocks a tool the free tier does not already have.

Which of these should a solo coordinator or small studio actually pick?

If you need to check, clean, convert and share IFC without buying seats, that is the case BIMCamel is built for. If you need an offline Windows viewer and never upload, BIM Vision. If you want to author openBIM for free, Bonsai. If a client mandates Solibri rulesets or your project is native Autodesk with 4D, buy the tool that does that — no comparison table changes a contract requirement.

Try it instead of reading about it

Every BIMCamel tool runs in the browser with no install and no account: validate a model, run clash detection, open the IFC viewer, or browse all 40+ tools. Pricing is on the plans page.

Before you act on any price here

Check the vendor's own site. Everything above was read from the vendors' own pages on the date shown with each product — the table was last verified end to end on 2026-08-07 — and every entry links to the page we read. Vendors change prices, rename tiers and withdraw free plans without notice, and this page does not update itself when they do. Spotted something wrong or out of date? Mail [email protected]; corrections from the vendors themselves are especially welcome.
