Own the React source.
Ship it through ReLayer.

Your UI stays in Assets/ReLayerUser. Open ReLayer Studio to validate, build, diagnose, and choose how the player receives it.

Before you start.

Source ownership, runtime dependencies, and the limits of UI-only updates.

Do I need to move my game to React?

No. Unity keeps your scenes, gameplay, assets, and game state. React handles the interface. Your Unity code handles the actions that the UI sends.

Can I edit the React source?

Yes. Your app lives in Assets/ReLayerUser. Change its components, styles, and themes; package updates do not overwrite it. Node.js is needed for editing and rebuilding, not for players.

Can I update UI without rebuilding the player?

Yes, after shipping a player that contains the delivery loader. Hosted selects immutable HTTPS releases; Addressables installs verified packages for offline reuse. C# and native changes still require a player release. Hot updates are not officially supported on WebGL.

Which platforms and architectures should I check?

Windows x64 uses WebView2. The packaged Apple backends target Apple Silicon macOS and arm64 iOS device/Simulator; Android includes arm64-v8a and x86_64. WebGL uses a browser DOM overlay. Check the platform requirements before purchasing.
