Neko
Self-hosted virtual browser with real-time multi-user streaming
Neko is a self-hosted virtual browser that streams a real Firefox session to your browser via WebRTC. Multiple users can watch and control the same screen simultaneously — perfect for watch parties, collaborative browsing, presentations, and private browsing. Low-latency video and audio, keyboard/mouse sharing, clipboard sync, and file upload built in.
Why Neko?
Sharing a browser session shouldn't require screen-sharing apps with lag and compression artifacts. Watch parties need synchronized playback that Zoom can't provide. Private browsing on a VPS keeps your real IP and fingerprint hidden. And collaborative debugging needs real-time shared control, not "let me share my screen".
How It Works
Neko runs a full Firefox browser inside a Docker container with a virtual display. It captures the screen and audio, encodes them in real-time, and streams via WebRTC to connected clients. Users interact through a web UI — their keyboard and mouse inputs are forwarded to the virtual browser. Admin controls who has input access.
What Is Neko?
Neko is an open-source virtual browser and remote desktop. It streams Firefox via WebRTC with sub-100ms latency. Supports multiple concurrent viewers, shared control with admin privileges, clipboard sharing, file drag-and-drop, microphone passthrough, and session persistence. Apache-2.0 licensed.
