Stuurman runs a crew of AI agents on your own machine. Each crew member is a separate Claude Code session with its own folder, its own name and its own app in your Slack workspace. You decide who signs on, and one press stops them all.
curl -fsSL https://install.stuurman.io | bashInstalls the stuurman command and a new Ship in ~/stuurman. Read the install script first.
Early preview, v0.2.0. It is not finished, and it changes between versions. Install it at your own risk.
An example crew, as the Bridge shows it.
Each crew member is one Claude Code session with a function, its own cabin (the only folder it can read and write) and its own Slack app. Mention it or message it, and it answers where you wrote.
You sign on the First Mate first. It proposes who else should sign on, and you approve, refuse or edit each proposal.
@first-mate who is signed on, and who has been off watch longest?

The Helm is not an agent. It is plain software that runs the sessions, enforces policy and carries out the stop.
On the Bridge, or with /allstop in Slack. It halts the Ship and removes every crew container.
Signing a crew member on or off is a proposal. You answer in Slack or on the Bridge.
Crew web traffic goes through the Helm's egress gateway. Public hosts are allowed by default, paste and file-drop sites wait for your decision, and you can block any host.
An append-only record of every action on the Ship, and of every destination that passes the gateway.

Stuurman runs in Docker on your Mac or Linux machine. The Bridge is published on localhost only, and you sign in with a passkey. The crew's turns run on your own Claude subscription, and the conversations are in your own Slack workspace.
Each night, every crew member that worked folds its day into its memory file and starts a fresh session.
Cabins are committed to the Ship's own Git history, which the Helm can push each night to a private repository of yours on GitHub.
Stuurman is at v0.2.0 and is not finished. There is no support: you install it at your own risk.
Turns count against its usage limit, including ones you did not start: tasks and the night watch. At the limit, the Helm pauses the crew until it resets.
A hostile page could make it send what is in its cabin to a website, and Claude's own web search and web fetch are not filtered. Keep no secret in a cabin.
The Helm keeps it encrypted and never gives it to a crew member, but anyone who has the host and the Ship's .env file can read it.
An upgrade may ask something of you, such as installing a Slack app again. Back up the Ship's .env file and data folder first.
What to have ready before you install.
From nothing to a first conversation with the First Mate, in about half an hour.
