Known Limitations

What doesn't (yet) work

Brewser aims for the full web platform, but it's an evolving runtime on constrained hardware. Current notable limitations:

For a detailed, per-pillar breakdown of HTML, CSS and DOM coverage, see Engine Status. This page collects the biggest gaps.

Web platform

  • WebGL conformance is a work in progress. Common paths are solid (major Three.js scenes run on real hardware); long-tail conformance tests still surface gaps. Report anything that behaves differently from Chrome.
  • Unity WebGL 2 exports are not yet supported (WebGL 1 exports work).
  • Video codec support is limited.

Platform

  • Touch input is handheld-only (hardware limitation).
  • Apps are expected to be self-contained; runtime module resolution is local-only.

Compatibility goal

Everything on this page is a bug or a roadmap item, not a design decision. The goal is unchanged: if Chrome does it, Brewser should too.
