Dear WebXR developers, For the last few weeks I've been working on a way to bring my next WebXR game, Fizzlings: Chain of Pop, to the Meta Quest Store. Not as a PWA. As a native app, with no browser and no WebView underneath. Presenting webxr-to-native. It's a native runtime that runs your unmodified WebXR build: V8 for the JS, WebGL2 over the device's own GLES driver (ANGLE on Metal/D3D), WebXR over OpenXR, WebAudio over the platform audio API. You add one host.json and get an APK. Targets: - Meta Quest (OpenXR), Fizzlings runs at 90 Hz. - Android phones, macOS, Windows, Linux, iOS (experimental, with an emulated headset or touch controls, so flat web 3D works too) - visionOS (experimental, simulator only so far) Tested with @threejs + IWSDK and @WebXREngine. It doesn't know about engines; it runs the bundle Vite gives it, so others may already work. What it gives us on Quest: - Native Platform SDKs: entitlement, user identity, leaderboards, achievements, age category, etc. - More headroom than the browser: ~2x the draw calls per frame of Quest Browser in my IWSDK benchmark on Quest 2, GL on its own thread - Chrome DevTools attach to it like a normal page - A path to platforms that don't run web tech (consoles are the goal) Caveats: it's early, it draws no HTML/CSS (your UI must be in built in WebGL. Expect rough edges. Try it out: github.com/Srile/webxr-to-na… (if you want to skip the build, grab the release) Many thanks to @squareys and @felix_trz for the inspiration and their help.
