I often run Claude Code and Codex side by side. Murmell lets them work in the same cloud workspace, with real terminals and file reservations, so I can see what each agent is doing without switching between multiple terminal windows.
The persistence worked well in my test. I started a shell command that waited 45 seconds before writing a completion marker to a file, left the project, and closed the browser tab. When I returned, the same Claude Code session was restored, the command had finished, and the file was still there.
It is more than a small multi-agent wrapper. Murmell keeps the workspace, terminal sessions, agent coordination, and Git snapshots together in one browser canvas.
