ReLayer – React UI Framework for Unity

ReLayer UI is a Unity UI workflow for building in-game HUDs, live-ops panels, menus, and overlays with React, Vite, HTML, and CSS.

Use familiar web development conventions and connect your React overlay to Unity through a structured C# to JavaScript bridge. This is useful for game HUDs, menus, live-ops panels, inventory, shop, reward, notice, and tool panels.

The package includes Unity runtime bridge components, platform WebView overlay integration, local overlay resource serving, a one-scene Initializer setup flow, an editable Vite/React overlay template, reusable UI kits, and a built Showcase scene. The Showcase runs from packaged files without Node.js.

Requirements and dependencies:

- Unity 2022.3 or newer.

- No Unity Package Manager or Asset Store package dependencies are required.

- Node.js 20.19+ or 22.12+ is required only to edit or rebuild the editable React/Vite source. The included Showcase runs without Node.js.

- Windows Editor Play Mode and Windows players require the Microsoft Edge WebView2 Runtime.

- Android builds require API level 21 or newer.

- Supported platforms in this release: Windows, Android, macOS, iOS, and WebGL.
