About Murmell

Murmell provides a shared browser canvas where multiple AI coding agents such as Claude Code, OpenAI Codex, Kimi Code, and Cursor Agent can run on a single cloud-hosted project directory. Each agent operates in its own terminal window within the same environment, allowing parallel execution of tasks. The platform enables real-time collaboration, with all participants seeing synchronized terminals, cursors, and live previews as changes occur. Agents reserve files before editing to prevent overlapping modifications, ensuring orderly collaboration. Users can start agents with a single prompt, assign tasks, and control multiple sessions from one interface. The system supports live preview functionality, allowing teams to review changes immediately. Projects remain active in the cloud even when no one is currently using them, resuming where they left off. The canvas can be shared with team members, enabling concurrent viewing and interaction.
