Cefious Web Browser brings Chromium-powered web technology directly into Unity, letting you run modern web experiences inside your app without opening an external browser. It also allows you to create fully local websites for your game, perfect for in-game interfaces, tools, and content.
Build in-game web views, dashboards, launchers, account portals, patch notes, storefronts, and internal tools with a developer-first workflow focused on reliability, flexibility, and production-ready performance.
Supports Unity Version 2022.3.62f3 + (fully tested on Unity 6+)

Context Menu & Interaction Control
- Custom context menu system with page-aware actions
- Built-in actions include copy, paste, open link, open in new tab, download, and save/copy image
- Add your own context actions or modify built-in behavior
URL Rewrite, Local Sites & Security
- URL Rewriter can map incoming URLs to custom targets, including local hosted content
- Build fictitious in-game websites from project content (example workflow included)
- Build-time security restrictions can limit which host/domain rules are allowed, helping reduce misuse
- Rewrite rules support custom security indicators: Configurable labels
Configurable active/inactive security icons per rule
Optional global icon/label overrides for consistent UX
- Address bar can display rewrite/fictitious state clearly so users understand when content is locally mapped
Remote Debugging
- CEF remote debugging can be enabled with a configurable local port (default commonly 9222)
- http://localhost:9222When enabled, Cefious exposes a local inspector endpoint such as:
- Open that URL in Chrome, Edge, or another Chromium-based browser to inspect active Cefious pages
- This lets you use familiar browser devtools workflows (DOM/CSS/script/network diagnostics) against pages running inside Unity
UI Flexibility
Whether you are building immersive in-game web experiences or robust developer tooling, Cefious Web Browser gives you a production-ready browser backend with an optional UI layer you can keep, adapt quickly, or fully replace.
