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.
Five things, in this order. Feature counts are not among them: they are the least useful
comparison in software, because every vendor ticks every box.
01
Setup effort in BIM software
What the first ninety days of a BIM software rollout cost in hours, not in licence fees. A product that needs a partner engagement before it does anything is a different purchase from one a team configures in an afternoon.
02
What BIM software really costs
What the bill becomes once the modules a normal buyer of BIM software needs are added, and whether you can read that number without a sales conversation.
03
Getting your data out of BIM software
How your own data comes back out, in what format, and whether that export is included in the BIM software contract or billed as a project.
04
Independence from the vendor
Whether you can buy BIM software, run it and leave it on your own terms. This test decides most of the order on this page, and it is why the largest vendors in BIM software often sit below the smaller ones.
05
Who the product is built for
The size and shape of company each BIM software product was actually built for. Most regret in software comes from buying for a company you are not yet.
The fourth test decides most of the order on this page, and it is the reason the largest
BIM software vendors sit below the smaller ones. A product with a published price, an export
that works and no mandatory implementation partner is a product you can leave.
A platform suite that arrives with a quote, a partner and a two-year commitment may well be
the better software and is still the harder decision to reverse. We rank BIM software for the
buyer who has to live with that decision without a procurement department, which is a stated
bias rather than a hidden one.
We do not publish a score out of ten. A number like 8.4 is a judgement dressed as a
measurement, and nobody can check it.
What you can check is on this page: what each BIM tool costs, where the vendor is
established, whether the price is published, and what we think it is bad at. Our full method
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 12 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. It is deliberately narrow: no authoring, no document control, and a plugin per authoring tool that needs attention each time those tools update.

NetherlandsPer user per month, published; free viewer
openBIM common data environment with a documented API
Ranked #2 of 12 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.

Rule-based model checking that fails a model against your standard
Ranked #3 of 12 in Best BIM Software in 2026.
Pricing on requestEurope
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 naming makes it easy to buy a version that cannot do this.
What stands out
Rule checking
IFC quality control
Classification audit

Writing useful rule sets is skilled work nobody budgets for
Cheaper editions omit the checking that justifies buying it
Right for
Clients and BIM managers auditing models they did not create
Wrong for

FinlandPer user subscription, quoted; tiered editions
Federated model and drawing coordination the site team will open
Ranked #4 of 12 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 does not check models, does not hold contractual documents and does not replace a CDE, so it is a third subscription rather than a consolidation, and licences are quoted.
What stands out
Federated navigation
Issue tracking
2D and 3D together

Quoted per licence and expensive across a large project team
No automatic checking and no document control
Right for
Mixed teams where non-modellers need to raise real issues

Buyers who expect a common data environment as well
Modular BIM platform with a genuinely free viewer tier
Ranked #5 of 12 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 12 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

Authoring that holds up on concrete, reinforcement and infrastructure
Ranked #7 of 12 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
Right for
Engineering offices doing concrete, reinforcement and bridge work
Wrong for
Practices that need to hire Revit-trained staff at short notice
Structural modelling detailed enough to drive the fabrication shop
Ranked #8 of 12 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
Fabrication level detail
Steel and concrete
Shop drawings

Model-linked scheduling and cost for 4D and 5D work
Ranked #9 of 12 in Best BIM Software in 2026.
Pricing on requestEurope
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. Quoted pricing, desktop-first, small support organisation.
What stands out
4D scheduling
5D cost
Rule-based grouping
Where it costs you
Results depend entirely on classification discipline in the model
Small vendor with limited partners outside central Europe
Right for
Contractors running 4D sequencing that has to survive programme changes

Teams whose models lack consistent classification data
File sharing and model viewing that is free until it is not
Ranked #10 of 12 in Best BIM Software in 2026.
Free tierPublished pricingNorth America
The free tier is the fastest way to get a federated model in front of everyone, and for a small project it is enough. 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.
What stands out
Free tier
Viewer included
Tekla integration
Where it costs you
Revision control and approval workflow are thin
Paid tiers assume you are buying other Trimble products

The authoring default, and the format everyone else works around
Ranked #11 of 12 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 #12 of 12 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.
What stands out
Clash detection
Model federation

Clash output is a list rather than a resolution workflow

United StatesPer seat annual subscription, published
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
7 of the 12 tools here publish what they cost; the other 5 quote per organisation, which means a sales conversation before you can compare anything. If you are buying without a procurement function, start with the ones that publish: BIMcollab, Catenda Hub, usBIM, Allplan, Trimble Connect, Autodesk Revit, Autodesk Navisworks.
02
Work out what the first ninety days cost in time
Licence cost is the number in the contract; setup effort is the number that surprises people. Ask every shortlisted vendor who does the configuration, how long it took the last customer of your size, and what happens if that person leaves halfway.
03
Check the exit before the entry
Ask for an export of your own data in a format you can open, and ask whether it is included or billed as a project. A vendor that hesitates here is telling you what renewal negotiations will feel like in three years.
04
Match the tool to the size you are, not the size you plan to be
Most regret in this category comes from buying for a headcount that never arrived. The entry-level products here are not worse; they are aimed at a different company.
05
Decide how much the jurisdiction matters
These 12 vendors are established in 8 countries across 2 regions (Europe 9, North America 3). Where a vendor is established decides which government can compel access to what it holds, which is a different question from where the servers are. For most buyers that is a factor, not a veto.
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
9 answers
What is the best BIM in 2026?
BIMcollab leads our ranking of 12. Issues live in an open BCF structure rather than a proprietary one, so the coordination record survives leaving the platform. The rule-based checker catches modelling errors before a clash meeting rather than during it.
It authors nothing and stores nothing: you still need a modelling tool and a document environment, and the publishing plugins need reinstalling every authoring-tool upgrade.
How did you rank these BIM tools?
On what separates products after the demo: how much setup the first ninety days take, what the price becomes once the modules a normal buyer needs are added, how your data comes back out, whether you can buy and leave it without a partner engagement, and who the product is genuinely for.
That fourth test is why the large platform suites usually sit lower here than their market share would suggest. Not on feature counts, and not on a score we invented.
Which BIM tools publish their pricing?
7 of the 12, with the pricing model each one publishes:
BIMcollab: Per user per month, published; free viewer.

What should you use instead of BIMcollab?
Catenda Hub and Solibri are the next two on this page.
Catenda Hub is for Projects that want a CDE without committing to one vendor's model format; Solibri is for Clients and BIM managers auditing models they did not create. All 12 are ranked here with what each one is bad at.
Who should not buy BIMcollab?
Anyone looking for one platform to replace the whole stack. Authors nothing and stores no contractual documents.
Do you get paid for these rankings?
Vendors can pay for visibility, which affects where and how prominently a product appears. It does not change a word of what the entry says about that product, including the criticism, and it cannot buy inclusion for something that does not belong in the category.
We take no commission when you click through to a vendor and we do not know whether you bought anything. The full arrangement is on our disclosure page.
How often is this BIM guide updated?
Whenever the facts move: a price change, an acquisition, a product that stops being maintained. The published and updated dates at the top of the page are real, and a review means someone went back to the vendor documentation rather than bumping a date.
These 12 products are the ones we judged worth ranking in BIM. If yours belongs here and is missing, tell us what it does and who it is for, and we will look at it. Inclusion is an editorial call and it is not for sale — but nobody gets considered for a list they were never put in front of.
People land on this page with a shortlist to make, not a browsing habit to feed. That is a narrower audience than a banner reaches and a far more decided one.
Written by us, about you
We describe the product in our own words, say who it suits and say who it does not. A vendor never writes the entry and never sees it before it goes up.
A correction costs nothing
If a fact about your product is wrong here, tell us and we fix it, whether or not there is any money between us. That offer is older than any commercial arrangement on this site.
Placement is separate, and disclosed
Where a product sits in the ranking can be paid for, and the notice above the list says so on every page. What the entry says about the product is not for sale at any price.
