About Murmell
Murmell is an innovative shared cloud canvas designed to bridge the gap between human development teams and AI agents. Operating as a unified workspace, it allows humans and AI to work together in the same room and on the same repository, complete with live previews and persistent cloud execution that keeps your projects moving even after you close your laptop.
Built to handle collaborative coding at scale, Murmell features a smart file-claiming mechanism where AI agents must claim files before writing to them. This ensures that people and agents can move simultaneously without risking overwritten code. Supporting a diverse lineup of models and tools including Claude Code, Codex, Kimi, and OpenCode—with future additions like OpenClaw and Hermes on the way—Murmell ensures that all completed work safely lands back in git so your projects are always right where you expect them.
