This page shows the current implementation status of the WebGPU API spec in browsers. It also lists some resources (samples, demos) for enthusiastic web developers. Also note the WebGPU Shading Language spec that's hosted separately.

The public-gpu@w3.org mailing list is a good place to ask questions or provide feedback on the API.

You can also join the chat on Matrix in the "Web Graphics" Matrix Community: #webgraphics:matrix.org. The general WebGPU channel is #WebGPU:matrix.org.

Implementation Status

Chromium (Chrome, Edge, etc.)

WebGPU has begun shipping to Mac/Windows/ChromeOS in Chrome 113 and Edge 113! As always, developers should develop against Chrome Canary or Edge Canary. Increased reach, other platforms, and bug fixes are ongoing.1

1 For details, look at the Dawn bug tracker and in the Chromium bug tracker Blink>WebGPU component. Search these before filing new bugs.
2 The chrome://flags/#enable-unsafe-webgpu flag must be enabled on these platforms (not enable-webgpu-developer-features). This flag is only available in Dev/Canary channels.
3 Linux experimental support also requires launching the browser with --enable-features=Vulkan,UseSkiaRenderer.

Firefox and Servo

These browser implementations are based on wgpu project in Rust.

Platform-independent features:

  • WGSL shaders
    • validation
    • overridable constants
    • behavioral analysis
    • uniformity analysis (present currently, but not up to spec)
  • buffer mapping
  • core features:
    • render bundles
    • compute
  • errors
    • error model
    • error scopes
    • graceful device lost handling
  • presentation
Platform-dependent features Vulkan D3D12 Metal

bounds checks ✔️ ✔️ (not needed) ✔️ (missing vertex pulling)

Firefox

In Nightly Firefox builds, WebGPU is enabled on Windows and Linux. For macOS and Android, users need to set the dom.webgpu.enabled pref to true.

All the issues and feature requests are tracked by the Graphics: WebGPU component in Bugzilla. For more details, see the Mozilla wiki.

Servo

Work in progress, enabled by "dom.webgpu.enabled" pref.

Safari (In Progress)

Work is in progress in Safari Technology Preview.

To enable WebGPU, first make sure the Develop menu is visible using Safari → Preferences → Advanced → Show Develop menu in menu bar. Then, in the Develop menu, make sure Experimental Features → WebGPU is checked. Avoid leaving it enabled when browsing the untrusted web.

Bugs can be viewed and filed here.
