Web Platform Support

Brewser's compatibility promise: if your app runs on Brewser, it runs in a desktop browser too. We implement standard web APIs with standard shapes, never custom brewser.* namespaces.

Broadly supported

• Modern JavaScript (ES modules, async/await, workers-adjacent patterns)
• fetch, WebSocket, and standard networking (see Networking and Multiplayer)
• Canvas 2D, WebGL 1, and WebGL 2 (see Graphics)
• Web Audio
• Gamepad API, Touch events, DeviceOrientation
• WebSerial, WebBluetooth, Web MIDI, Web NFC (see Hardware APIs)
• localStorage and app-scoped storage

Practical development loop

Because Brewser apps are standard web apps, the recommended workflow is:

1. Build and iterate in Chrome on your desktop.
2. Test on Brewser (emulator or real hardware) for performance and device-specific behaviour.
3. Submit via the publishing pipeline.

Engine completeness

The HTML, CSS and DOM engine is from scratch, so coverage varies by feature. For a per-pillar breakdown of what works and what doesn't yet, plus the gap lists that double as the contribution roadmap, see Engine Status.
