Rustpad

Rustpad is an efficient, minimal collaborative text editor for writing code together in the browser. It uses an operational transformation (OT) approach for real-time collaboration and is designed to be lightweight, with no database required by default.

Key Features

• Real-time collaborative editing over WebSocket connections
• OT-based synchronization designed for low-latency concurrent editing
• Monaco Editor-based web UI (VS Code editor component)
• In-memory document storage with automatic garbage collection for inactive pads
• Optional persistence via SQLite snapshots to retain documents across restarts
• Simple deployment as a small Docker image

Use Cases

• Pair programming and live code review sessions
• Sharing temporary collaborative notes or code snippets during incidents
• Lightweight collaborative editor for internal teams without heavy dependencies

Limitations and Considerations

• By default, documents are transient and can be lost on restart or after the inactivity expiry window unless SQLite persistence is configured

Rustpad is a good fit when you want a fast, no-frills collaborative editor that is easy to deploy and operate. Its minimal architecture and optional persistence make it practical for temporary collaboration as well as lightweight long-running installations.
