Two agents. One file. No rules.
The agent dies with your laptop.
Four clones, and a Friday of merges.
Start agents with one prompt
Describe the work once. Murmell opens the terminals and assigns the tasks to the agents you choose.

File reservations
An agent reserves a file before editing it. Other agents wait until that file is available, which prevents overlapping changes.

FAQ
What is Murmell?
Murmell is a browser canvas where several AI coding agents (Claude Code, Codex, Kimi, OpenCode) run on a cloud machine and share one project directory. Each agent opens in its own window with a real terminal, and everyone on the link sees the same canvas as it happens.
Can several people really use one canvas at the same time?
Yes. Everyone on the link sees the same room: who joined, which window they are watching, where their cursor is. Each person drives their own agents, and nothing has to be replayed or refreshed to stay in step.
Where does my code live?
On a machine Murmell runs, in one directory, and in a private GitHub repository created with the project. The workspace is disposable and the repository is not: the work is pushed before a machine is ever torn down.
How much does Murmell cost?
Murmell is a paid product: Solo $39, Pro $69, Builder $149 per month, billed monthly, or ten months' price for a year. Pro starts with a 48-hour free trial. Solo and Builder are charged immediately. Read links, watching a canvas somebody shared, are free and uncapped, and cost the viewer nothing and no account. Murmell charges for the machines and the room, never for model tokens: you connect the agent subscriptions and API keys you already pay for.
Do you resell tokens?
No. You connect the agent subscriptions and API keys you already pay for. Murmell charges for the machine and the collaboration, never for the model.
What stops two agents destroying each other?
An agent claims the paths it is about to touch before it writes. A watcher attributes every write back to whoever made it, and a colliding write is snapshotted before it lands, so nothing is lost. The rule is enforced by the machine rather than suggested to the model.
Is each project isolated?
Yes. Every canvas runs on its own machine, separate from every other project Murmell hosts. The machine that executes agent code holds no database and no decryption key.
Which coding agents does Murmell support?
Claude Code, Codex, Kimi and OpenCode today, each in its own terminal on the canvas, signed in with your own account or API key. Adding an agent is adding a tile: nothing about the canvas changes.
Can I self-host it?
No. Murmell runs the machines for you. That is the product. Your code still ends up in a private repository you own.
