And even that isn't enough; no browser supports WebGPU on all platforms out of the box. https://caniuse.com/webgpu

Chrome supports it on Windows and macOS, Linux users need to explicitly enable it. Firefox has only released it for Windows users, support on other platforms is behind a feature flag. And you need iOS 26 / macOS Tahoe for support in Safari. On mobile the situation should be a bit better in theory, though in my experience mobile device GPU drivers are so terrible they can't even handle WebGL2 without huge problems.
