Lightweight Browser

A lightweight multi-platform native webview plugin for Unity that renders web content as Texture2D, allowing Unity UI and game objects to draw on top.

Key Features

  • 5 platforms — Windows (WebView2), Android (System WebView), iOS (WKWebView), macOS (WKWebView), Linux (WebKitGTK)
  • Texture-based rendering — Web content rendered to Texture2D, pipeline-agnostic (Built-in, URP, HDRP)
  • Bidirectional JS ↔ C# bridge — window.unityBridge API with send, call, on/off patterns
  • One component setup — Add LightweightBrowser to any GameObject, set a URL, press Play
  • Auto-resize — ScreenResizeHandler detects resolution changes and adapts
  • Debug overlay — Real-time bridge message inspector (F12)

Prerequisites

  • Unity 2022.3 LTS or newer (Unity 6 recommended)
  • IL2CPP scripting backend recommended (Mono supported on desktop)
  • Linux only: install libwebkit2gtk-4.1 and libgtk-3 via your package manager
