TL;DR

Both are free, but they work very differently. model-viewer is a developer library: you add it to your page and set it up in code (HTML and JavaScript). Trice is a no-code studio that does the hard parts for you and gives back a ready, shareable result. It runs on a modern WebGPU engine, so models look great and stay smooth even on heavy scenes. You just import a model, and it is automatically optimized and ready to make interactive without touching code.

The verdict

It comes down to control versus convenience. model-viewer is free, open source, and completely yours: no account, no vendor lock-in, a tiny self-contained component you drop into your own code that keeps working offline. If you want that level of control, you are comfortable working in code, and you mainly need to drop a model onto a page, that is exactly what model-viewer is built for.

For almost everything else, Trice is the better fit. The core difference is that it is all no-code: you build and configure the whole scene in a visual editor instead of writing and maintaining code. On top of that come things that are hard to match, and one of the strongest is optimization: every model is automatically compressed, often many times smaller, so pages load fast and stay smooth even on heavy scenes, while model-viewer leaves that to you. Your model also looks great the moment you import it, with more advanced shading and built-in post-processing, and you can import almost any format, compose multiple models, edit materials, and add hotspots, variants, and camera tours, then share it all with a single link. Progressive texture loading is a bonus on top, revealing scenes instantly while full-resolution textures stream in.

So the conclusion is simple. Unless you specifically need a fully open-source solution with no dependencies, Trice is a polished, full-featured product that gets you a better result with far less effort, and it only keeps getting better as we ship updates and act on what users ask for.

Questions

Because the free plan is self-hosted: you host your model files and we provide the renderer at no cost, which costs us very little to support, so we keep it free with no watermark. If you would rather we host your files for convenience, Pro is $8/month, and that is what keeps the product running.

No. Trice is no-code: you import a model, set everything up in a visual editor, and share it with a link or an embed. model-viewer, by contrast, is configured in HTML and JavaScript, so it expects some development work.

Easily. Drag your model into Trice (GLB, glTF, FBX, OBJ, and more) and it imports and optimizes automatically. Set the scene up in the visual editor, then share it with a link or embed it on your page.

No. Trice compresses geometry with meshopt and converts textures to WebP, which can make files many times smaller with no visible quality loss.

No. Trice optimizes every model so it stays light, and the renderer drops to zero GPU usage the moment the camera stops moving. You can put several scenes on one page and it stays fast.

Yes, and optimization is a big part of why. Trice shrinks both geometry and textures, which keeps VRAM usage low, so scenes do not exhaust a phone's memory and crash the page the way they often do with other viewers. With strong rendering performance and smooth touch controls on top, scenes stay fast and stable on mobile.

Quite possibly. We are a small team that ships fast and listens to our users. If a request makes sense for the product, there is a good chance we will build it, so it is always worth asking.
