Cloud IFC Validator without the upload
A cloud IFC checking tool normally means sending the model to someone else's server. This one is a web page that does the work in your own browser: same convenience, and the file never leaves your computer.
No account. Works in Chrome, Edge, Firefox and Safari. Up to 2 GB per file.
Upload or browser
A checking service that uploads, and a page that does not
Solibri WebChecker is the clearest published example of a cloud checking service, so it is the comparison here. Its column quotes Solibri's own page.
| Solibri WebChecker (Beta) | IFC Viewer Online | |
|---|---|---|
| Where the model goes | Uploaded to the service. Data is stored in the EU or the US, chosen when the project is set up | Nowhere. It is read in your browser tab |
| How long results are kept | 30 days, then removed | Until you close the tab. You keep what you export |
| File size | Up to 5 GB per IFC file | Under 2 GB per file, and less on a computer with little memory |
| Account | A Solibri ID and a Solibri Advanced or Premium plan | None |
| Cost of a check | 50 tokens. Advanced includes 1,750 tokens a year, Premium 17,500; a pack of 5,000 tokens costs €250 | Free |
| Checks | Solibri's Model Health check, or a custom ruleset (.cset) prepared in the Solibri desktop application | 44 fixed rules and your IDS 1.0 files |
| Results | PDF and BCF; SMC files with Premium | BCF 2.1, CSV, JSON, HTML report, COBie spreadsheet. No PDF file: the HTML report prints from the browser |
A server earns its place when files are larger than a browser can hold, when results must stay available to a whole project team, or when checks have to run unattended. None of that happens here: this page checks one person's file on that person's computer.
The browser wins when the model may not leave the building, when nobody will approve a new supplier this week, or when you just need an answer about one file.

Scope
What it checks, and what it does not
It checks
- 44 rules in eight groups: identifiers, spatial structure, storeys, names, property values, types, materials, export quality. 25 run by default.
- IDS 1.0 files, with the six facets: entity, attribute, property, classification, material and part-of.
- Five built-in validation profiles (basic delivery, quality review, BIM coordination, ISO 19650, LOD 300), or your own.
It does not check
- Clashes between models. Only bounding boxes inside one model, off by default.
- Building codes or design rules written for your project. There is no rule editor; requirements go in as IDS.
- Batches. Each file is opened by a person; nothing runs on a schedule.
Limits
Limits, with numbers
| Limit | |
|---|---|
| File size | 2 GB per file is refused. A notice appears from 200 MB and a memory warning from 1 GB; on phones, tablets and computers with 4 GB of memory or less it starts at 80 MB. |
| Formats | IFC2x3, IFC4, IFC4x1 and IFC4x3, as .ifc or inside .ifczip and .zip. |
| IDS | IDS 1.0. The restrictions totalDigits, fractionDigits and whiteSpace are not read. Up to 200 failing elements are listed per specification. |
| Sharing | A share link carries the score and the first 50 issues inside the URL, up to 8,000 characters. The model is not in it. |
| Connection | The page has to load from the internet. It does not work offline. |
Your file
What happens to the file
The IFC is opened by code running in your browser tab and is not sent anywhere. You can check it yourself: open the browser's developer tools, watch the Network tab and drop a file.
The browser keeps a converted copy of the geometry in its private storage on your computer (up to 4 GB) to reopen the model faster. Clearing the site data removes it.
Usage statistics without cookies record the file size and the number of elements, never the content, and can be switched off. A share link, if you create one, contains the score, the file name and up to 50 issues with element names.

Price
What it costs
Nothing: the viewer, the rules, IDS and the exports are free and need no account. The code is public under the MIT licence on GitHub.
Paid plans that add a server (stored models, saved rule sets, team work) are described on the pricing page and are not on sale yet.
FAQ
Questions
Is this a cloud service?
It is delivered from the web like one, but the checking is done by your browser. There is no upload, no queue and no stored copy of the model on our side.
How can I verify that nothing is uploaded?
Open the developer tools of your browser, go to the Network tab and drop an IFC file. You will see the page's own files load and no request carrying the model.
How large a file can it take?
Files of 2 GB or more are refused, and the practical limit depends on the memory of the computer: a warning appears from 1 GB, or from 80 MB on phones and machines with 4 GB of memory or less. Solibri WebChecker accepts up to 5 GB per file (solibri.com/solutions/webchecker, read on 2026-11-10).
Can I automate it?
Not from this page: each file is opened by a person. There is an MCP server (ifc-viewer-mcp) that runs the same validation on your own machine from an assistant or a script; see the source on GitHub.
Is it allowed for confidential models?
The model stays on your computer, which is usually what an NDA asks for. Check two things against your own policy: the anonymous usage statistics (they can be switched off) and the share links (they contain file and element names).
