Browser-based IFC viewer
Bimlyte is a browser-based IFC viewer: it opens and displays IFC BIM models directly in your web browser, with no desktop software to install.
Review models on Windows, macOS, Linux, tablets and phones — the same tool everywhere, nothing to set up.
How it works
- Open Bimlyte in your browser.
- Load your IFC file from your device.
- View geometry, inspect data and work with BCF issues.
How a browser opens a real BIM model
"It runs in a browser" used to imply a toy. It no longer does, and it is worth knowing why — three browser capabilities do the heavy lifting:
- WebAssembly runs compiled code at near-native speed inside the browser. Bimlyte parses IFC with web-ifc and Fragments from That Open Company, the same open-source engines behind many browser BIM tools — so reading the schema is compiled work, not JavaScript grinding through a text file.
- WebGL draws the geometry using your machine's graphics hardware, which is the same hardware a desktop viewer would use for the same job.
- The Origin Private File System (OPFS) gives the app fast, private storage on your own disk, isolated from other sites. This is what lets a large model live on your device between sessions instead of being re-parsed every time.
What this means for large models
Because the work happens on your machine, the ceiling is your machine. Bimlyte imposes no file-size limit; a large federated model will simply load more slowly on a phone than on a desktop with plenty of RAM, exactly as it would in a desktop application.
It also means performance does not depend on your connection or on how busy someone's server is, because neither is involved in drawing the model.
Nothing to install, nothing to administer
The practical wins are mostly about what you no longer have to arrange:
- Runs in modern browsers on Windows, macOS and Linux — no separate build to obtain per platform.
- The same IFC and BCF features on tablets and phones.
- No admin rights needed, which matters on a locked-down work machine where installing software is not an option.
- No licence server, no seat management, no IT ticket.
- Nothing to update — every visit loads the current version. It can also be installed to the device and used offline.
Which IFC versions it reads
Bimlyte opens IFC2x3, IFC4 and IFC4x3. That range matters in practice: IFC2x3 dates from 2006 and is still what many established export presets produce, while IFC4 is standardised as ISO 16739-1:2018 and IFC4.3 — covering infrastructure such as roads, bridges and rail — was approved as ISO 16739-1:2024.
Running in the browser keeps your model with you
Browser-based and cloud-based are routinely confused, and they are not the same thing. Bimlyte handles your IFC model on your own device and does not upload it to a server in order to display it.
Frequently asked questions
Do I need to install anything to use Bimlyte?
No. Bimlyte is browser-based, so there is nothing to download or install, and no admin rights are needed.
You open it as a web page and load your IFC file. If you want it on your device, it can also be installed as an app in one click and used offline.
Which browsers does Bimlyte work in?
Bimlyte runs in modern web browsers on Windows, macOS and Linux, and on mobile devices.
It uses WebAssembly, WebGL and the Origin Private File System, so a browser kept up to date gives the smoothest experience.
Does the browser-based viewer work on mobile?
Yes. The same IFC and BCF features are available on tablets and phones, not just desktop.
The practical difference is hardware rather than features: a phone has less memory, so a large federated model loads more slowly there.
Can a browser really handle a large IFC file?
Yes. Modern browsers parse IFC as compiled WebAssembly, render with WebGL through your graphics hardware, and store files on disk via the Origin Private File System — so the work runs at close to the speed a desktop application would manage.
The limit is your device's memory rather than the browser or any cap Bimlyte applies.
