Browser & device compatibility

WebGPU is a requirement, not a performance promise. Check your actual browser and GPU.

Reviewed October 11, 2026

Desktop is the starting point

Use an up-to-date Chrome or Edge release with hardware acceleration and a supported GPU. The upstream README lists Chrome/Edge 113+ with WebGPU, but version numbers alone are not a guarantee: operating systems, graphics drivers and browser policies can affect availability.

The project’s loader also mentions Safari 26+ and Firefox 141+ with WebGPU enabled. We have not verified those browser/OS combinations. Use our homepage’s browser check to confirm that an adapter is available in your current session.

What the browser check measures

The check looks for a secure context, the WebGPU API, and a result from navigator.gpu.requestAdapter(). It does not run a game benchmark, test memory capacity, or prove that a particular map will load. It does not upload the result.

Phones and tablets

The upstream build includes on-screen gamepad controls and a lighter rendering mode. On touch devices, our launcher requests both. This is experimental support: large downloads, shader compilation, memory pressure and heat may still prevent a useful session.

We have not completed physical iPhone, iPad or Android tests. A mobile-sized layout check only proves our guide fits the screen. For touch devices, opening the game in a separate tab may give the controls more space.

Black screen or slow startup

1. Wait for the first engine download and shader compilation to finish.
2. Run the WebGPU check and confirm browser hardware acceleration is enabled.
3. Close other demanding applications and tabs, then retry in a current browser.
4. Start with KenneyPark. Larger maps can require substantially more memory and loading time.
5. If fullscreen, storage or input fails, end the session and retry in a supported desktop browser. Use our Fullscreen toolbar button for more space.
6. If the upstream game reports a network error, try again later. This guide does not operate its hosting.

What we actually tested

On October 11, 2026, a cross-origin iframe in desktop Chrome rendered KenneyPark and responded to keyboard push input. The game’s FPS overlay showed about 60 during that smoke test. It was a short functional test, not a measured benchmark or a cross-device certification. Multiplayer and physical gamepads remain untested by this site.
