Neko

Neko is a self-hosted “shared browser” that streams a real browser running in a container to multiple participants, keeping everyone in sync. It’s commonly used for watch parties and collaborative browsing, where users can see the same tab and optionally take turns controlling it.

Key Features

• Streams a full browser (Firefox/Chromium) from a container to users via WebRTC
• Multi-user rooms with shared, synchronized session state (everyone sees the same page)
• Remote control support (mouse/keyboard) with configurable permissions/turn-taking
• Built-in chat for coordinating during sessions
• Audio/video streaming suitable for watch parties and shared media playback
• Designed to run behind reverse proxies; configurable networking and security options via environment variables

Use Cases

• Watch parties for streaming sites where participants need a synchronized shared browser
• Remote collaboration for pair browsing, demos, or guiding non-technical users through web flows
• Quick “disposable” browser sessions for testing websites in an isolated container

Limitations and Considerations

• Requires WebRTC-capable clients and network paths; NAT/proxy setups may need additional configuration
• Performance and responsiveness depend on server resources and available uplink bandwidth

Neko is a practical way to host a real browser centrally and share it live with a group. It fits teams and communities that need synchronized viewing and lightweight collaborative control without installing client software beyond a modern browser.
