BIM is sold as one acronym covering three unrelated purchases: the tool that authors the model, the tool that coordinates disciplines and tracks clashes, and the environment that holds the files everyone works from.
This guide separates them, ranks each on what it costs to leave, and says where IFC actually breaks.
Vendors can pay for visibility on this page. It never changes what an entry
says about a product, including the criticism, and we earn nothing when you click through to a
vendor. How that works.
In short
What BIM software does
BIM software creates, checks and shares a three-dimensional building model in which every object carries data, so design, construction and handover work from one source.
In this order: setup effort, what it really costs, how your data comes back out, whether
you can leave, and who each BIM tool is built for. Why those five, and why there is no
score out of ten, is on the how we work page.
Contractors whose BIM execution plan names it explicitly
Teams that want issue tracking and clash detection in one tool
Country is where the vendor is headquartered or contracts from, which is a
different question from where your data is hosted. Where the two tell different stories, the
entry says so.
Issue management and model checking built on open BCF
Ranked #1 of 19 in Best BIM Software in 2026.
Published pricingEurope
Issues are stored as BCF, which means the coordination history exports into anything else that reads BCF instead of dying with the subscription. The rule-based checker runs against a delivered model before the meeting, so clash sessions argue about resolutions rather than about whether the model is even valid.
Twin, the document-management side, adds metadata, version tracking and approval workflows, so it is no longer only a coordination layer. It still authors nothing, and needs a plugin per authoring tool that needs attention each time those tools update.
What stands out

Where it costs you
Authors nothing, and the document side is younger than its BCF coordination

openBIM common data environment with a documented API
Ranked #2 of 19 in Best BIM Software in 2026.
Published pricingEurope
Catenda treats IFC and BCF as native rather than as an export, so the common data environment does not quietly become a reason you can never leave. The API is documented well enough to build reporting or integrations against, which is rare here.
Weaknesses are predictable for a small Nordic vendor: document control is functional rather than deep, very large federated models tax the viewer, and support outside Scandinavia depends on a short partner list.
What stands out
openBIM CDE

Federated model and drawing coordination the site team will open
Ranked #3 of 19 in Best BIM Software in 2026.
Pricing on requestEurope
Revizto's advantage is social rather than technical: drawings and the federated model share one navigation, so a site engineer or a client representative can find a problem and raise it without opening a modelling tool.
Issue volume from outside the BIM team rises measurably. It runs clash detection but not rule-based checks of model quality, does not hold contractual documents and does not replace a CDE, so it is a third subscription rather than a consolidation, and prices are quoted.
What stands out
Federated navigation

Rule-based model checking that fails a model against your standard
Ranked #4 of 19 in Best BIM Software in 2026.
Published pricingEurope
Solibri answers a question the rest of the category avoids: is this delivered model actually usable. It checks classification, naming, spaces, duplicates and anything else you encode as a rule, which is how a client enforces an information requirement instead of hoping.
The cost is a person: rule sets have to be written and maintained against your own standard, and a default rule set produces noise. Edition prices are published, but the ladder is easy to misread: Starter does no rule checking, Essential runs only predefined rules, and custom rules start at Advanced.
What stands out
Rule checking
IFC quality control
Classification audit
Where it costs you
Writing useful rule sets is skilled work nobody budgets for
Custom rules need Advanced or above; Starter does no rule checking at all

Modular BIM platform with a genuinely free viewer tier
Ranked #5 of 19 in Best BIM Software in 2026.
Free tierPublished pricingEurope
ACCA's free tier is a real product rather than a trial: a viewer and file store that lets a small office share IFC models properly. Paid modules cover authoring, checking, quantities and more, each priced low and each doing less than the specialist equivalents on this page.
The risk is buying six modules to approximate one competitor. English documentation trails the Italian, and support conversations tend to go the same way.

Model access on a phone for people who never open a modeller
Ranked #6 of 19 in Best BIM Software in 2026.
Pricing on requestEurope
StreamBIM assumes the reader is standing in the building, not sitting in a design office. Large federated models open quickly on a tablet, object data is one tap away, and checklists and handover records attach to the objects rather than to a separate app.
That focus means it does nothing for design coordination and authors no geometry. Per-project subscriptions match how contractors budget and irritate consultants who want a seat they keep.
What stands out
Site access
Mobile first
Checklists
Where it costs you
Authors nothing and is weak on design-side coordination
Per-project pricing suits contractors, not consultants
Right for
Site teams and handover, where the model has to load on a tablet
Wrong for
Design offices coordinating disciplines before construction
Speckle treats a model as data rather than a file: a Revit wall, a Tekla beam and a Rhino surface go to one project as objects with versions, and each discipline receives them in its own tool.
That fixes a lot of what IFC round trips break. It is a layer beside the BIM stack, though. There is no clash detection, no formal approval workflow, and it only pays off when every team installs the connectors.
What stands out
Interoperability

Browser-based BIM authoring with live collaboration and Revit exchange
Ranked #8 of 19 in Best BIM Software in 2026.
Free tierPublished pricingNorth America
Snaptrude's case is collaboration and access: a design team edits one model in the browser at the same time, and the result moves into Revit when the project needs it. For feasibility and concept work that removes a licence and a workstation from each seat.
The limits come later in a project, where detailing and drawing sets remain Revit or Archicad work, and a small company means its roadmap and survival are worth asking about.
What stands out

Authoring that holds up on concrete, reinforcement and infrastructure
Ranked #9 of 19 in Best BIM Software in 2026.
Published pricingEurope
Allplan's reinforcement and cast-in-place concrete modelling is better than what the market leader offers, and its infrastructure and bridge modules reflect years of European engineering practice. Inside German-speaking Europe the trained labour exists.
Outside it, recruitment becomes the constraint: a practice can buy the licence and then fail to staff it. The architectural workflow is serviceable but rarely the reason anyone switches, and the learning curve is real.
What stands out
Reinforcement detailing
Infrastructure
IFC export
Where it costs you
Steep learning curve and a thin pool of trained users outside DACH
Architectural side is weaker than its structural and infrastructure side

Web-based BIM coordination and issue tracking for design and construction teams
Ranked #10 of 19 in Best BIM Software in 2026.
Pricing on requestNorth America
Konekt combines what used to be BIM Track, a browser issue tracker for federated models, with Newforma's project information tools, so a clash, the email about it and the drawing it affects sit in one place.
For an architecture or engineering firm already on Newforma that removes a system. It checks nothing itself, the combined product is still settling, and outside North America the user base and partner support are smaller.

London common data environment for ISO 19650 project delivery
Ranked #11 of 19 in Best BIM Software in 2026.
Published pricingEurope
Asite answers the third of the BIM purchases, the environment everyone works from, and answers it for the party that sets the rules: the client or main contractor who needs every drawing, model and approval traceable.
ISO 19650 status codes, transmittals and audit trails are what it is bought for. The weight follows from that. Configuration is a project, only starting prices are published, and design teams often keep their own coordination tool alongside it.

Structural modelling detailed enough to drive the fabrication shop
Ranked #12 of 19 in Best BIM Software in 2026.
Pricing on requestEurope
Tekla models connections, bolts and reinforcement at the level a fabrication shop needs, then produces the drawings and machine data directly from that model. No general authoring tool does this credibly, which is why it survives at a premium price.
The cost is specificity: the configurations differ substantially in what they allow, the quote depends on which one you pick, and at design-stage detail you are paying for capability you will never open.
What stands out

Model-linked scheduling and cost for 4D and 5D work
Ranked #13 of 19 in Best BIM Software in 2026.
Published pricingEurope
BEXEL links model objects to schedule activities and cost items through rules, so when the programme changes the 4D sequence updates instead of being rebuilt by hand. That is the difference between 4D as a live tool and 4D as a one-off video for a bid.
The dependency is uncomfortable: rules need classification, and most delivered models are inconsistent. Expect to fix the model before the tool pays back. Published annual prices, desktop-first with cloud modules alongside, small support organisation.
What stands out

4D construction planning that links the schedule to the model
Ranked #14 of 19 in Best BIM Software in 2026.
Published pricingNorth America
SYNCHRO turns a schedule into something a site team can watch: activities linked to model objects, with temporary works, cranes and logistics shown in sequence. It reads Primavera P6 and Microsoft Project, so the planner keeps their tool.
The cost is money and skill, since the licence is priced for large contractors and the software needs a trained operator. As with BEXEL Manager, results depend on a well-classified model.

Engineering work-in-progress and document management for infrastructure projects
Ranked #15 of 19 in Best BIM Software in 2026.
Published pricingNorth America
ProjectWise was built for the problem infrastructure design actually has: thousands of drawings and models referencing each other, edited by several firms, where a broken reference is a wrong drawing. It handles that better than general document tools.
The price is administration: someone configures the environment, workflows and permissions, and Bentley or a partner is usually involved. On a building project, lighter openBIM environments do the job with less effort.
What stands out

Project-wide common data environment with an unalterable audit trail
Ranked #16 of 19 in Best BIM Software in 2026.
Pricing on requestNorth America
Aconex is chosen by the client side of large projects because each participating organisation keeps ownership of its own documents and the audit trail cannot be edited afterwards, which is what a dispute needs.
Transmittals, correspondence and model viewing sit in one record. It is an Oracle sale, configured through account teams, and the handover archive should be specified in the contract at the start, because the record is only as portable as that clause.

File sharing and model viewing priced per user per year
Ranked #17 of 19 in Best BIM Software in 2026.
Published pricingNorth America
Pro and Innovate are sold per user per year at listed prices, which makes it a quick way to get a federated model in front of everyone, and for a small project it is enough. There is a 30-day trial but no permanent zero-cost plan.
What it is not is a controlled document environment: revisioning is basic, approval routing barely exists, and there is no transmittal record a contract administrator would accept. Tekla users get the tightest integration, which is also the commercial logic: the paid tiers make most sense inside the wider Trimble estate.

The authoring default, and the format everyone else works around
Ranked #18 of 19 in Best BIM Software in 2026.
Published pricingNorth America
Revit is the default because hiring, collaboration and client requirements all assume it, and the add-in ecosystem compounds that year after year.
Judged on the tests this site applies, it is the weakest exit on the page: the native format is effectively closed, IFC export loses parametric behaviour, and subscription costs have risen steadily with a licensing change that removed the flexibility smaller practices used. Buy it for market compatibility, and budget for never leaving.

Clash detection most contractors still specify by name
Ranked #19 of 19 in Best BIM Software in 2026.
Published pricingNorth America
Navisworks federates almost any format and runs clash tests across very large models reliably, which is why it is still written into execution plans.
The problem is what happens after the test: the output is a report, so teams export to BCF and manage resolution somewhere else, paying for two tools. The product has seen little meaningful development in years, runs only on Windows, and NWD is a poor archive format.

BIM software creates, checks and shares a three-dimensional building model in which every object carries data, so design, construction and handover work from one source. The differences that matter are rarely in the feature list, so this is
the order we would work through them.
01
Decide whether you need a published price
14 of the 19 tools here publish what they cost; the other 5 quote per organisation. The ones you can compare without a sales call: BIMcollab, Catenda Hub, Solibri, usBIM, Speckle, Snaptrude, Allplan, Asite, BEXEL Manager, Bentley SYNCHRO 4D, Bentley ProjectWise, Trimble Connect, Autodesk Revit, Autodesk Navisworks.
02
Decide how much the jurisdiction matters
These 19 vendors are established in 9 countries across 2 regions (Europe 11, North America 8). That decides whose disclosure law applies to what the vendor holds, wherever the servers are.
03
Consider whether you want the source
1 of these are open source: Speckle. Hosting one yourself trades a subscription for maintenance.
Three products, one acronym: authoring, coordination, environment
Nobody sells BIM. They sell one of three things. Authoring creates geometry and data: Autodesk Revit, Allplan and Tekla Structures. Coordination federates other people's models and tracks what is wrong with them: Revizto, Solibri, BIMcollab and Autodesk Navisworks.
A common data environment holds the files, the revisions and the record of who issued what: Catenda Hub and, loosely, Trimble Connect. A quote that appears to cover all three is usually strong at one and thin at the others. Decide which of the three you are actually short of before you take a demo, because every vendor will happily demonstrate the other two.
Write down which of the three functions is failing today. Buy for that one.
Ask which of the three the product was originally built to do.
If one vendor covers all three, price the two weakest parts against a specialist.
Where BIM stops and CAD and construction management begin
Three lines get blurred in sales conversations. CAD produces drawings, and a drawing is a picture; BIM produces objects that carry data, and the drawing is a by-product. A tool that exports a 3D DWG is not doing BIM. The second line: construction management software runs the site — RFIs, snagging, day diaries, payment.
Model coordination is design-stage work, which is why StreamBIM sits on the boundary and does site work with model data rather than replacing either. The third line is the common data environment, which is a document-control function that happens to hold models. Buying a coordination tool and calling it a CDE fails the first contractual audit.
Ask whether objects carry classification and property sets, or just geometry.
Check whether the tool is intended for design stage, site stage, or both.
Confirm whether the product can produce a transmittal record with an audit trail.
IFC works in theory and degrades in practice
IFC is the reason to believe you can leave a vendor. It is also why exports disappoint. Geometry survives; parametric behaviour does not — a wall arrives as a shape, not as a wall that knows how to host a window. Property sets survive only if the authoring tool mapped them, and each does it differently.
Classification codes drop silently when nobody set them. This is why Solibri and BIMcollab exist: checking the IFC is a separate job from producing it. Treat IFC as a reliable archive and exchange format, and as an unreliable round-trip. Models come back from IFC as references, not as editable design.
Export your own model to IFC and reimport it into a different tool before signing.
Check whether property sets and classification codes survive the trip.
Agree the IFC version and the required property sets in the contract, not in an email.
What leaving costs, and who is holding the model
Ask the exit question early, because in this category it has a real answer. BIMcollab stores issues as BCF, so the coordination record is portable. Catenda Hub holds IFC as the native object, not as an export. Autodesk Revit's RVT is readable only by Autodesk, and Navisworks NWD is worse as an archive than the IFC you could have kept instead.
The question that matters at handover is what the client receives: a federated model in an open format with a documented property set, or a folder of proprietary files that need a live subscription to open in ten years.
Define the handover deliverable as open formats in the contract, at the start.
Ask what a full export contains and how long it takes to produce.
Check whether issue history and comments come out, or only the models.
What goes wrong most often when buying BIM software
Buying a coordination tool and calling it a common data environment, then failing the first document audit.
Assuming IFC round-trips. It exchanges and archives well; it does not return editable parametric design.
Letting the authoring tool choice be made by whoever is available to hire, then discovering the licence model changed.
Running clash detection without a rule check first, so the meeting argues about a model that was never valid.

Frequently asked questions
8 answers
What is the best BIM in 2026?
BIMcollab leads our ranking of 19. Issues live in an open BCF structure rather than a proprietary one, so the coordination record survives leaving the platform.
The rule-based checker in Zoom catches modelling errors before a clash meeting rather than during it, and Twin now adds document management with approval workflows. It authors nothing, so you still need a modelling tool, and the publishing plugins need reinstalling every authoring-tool upgrade.
