Quick Start#

1. Initialize your project#

cd ~/projects/my-app
claustro init

This walks you through a setup wizard and creates claustro.yaml. Use claustro init -y to accept all defaults.

2. Start a sandbox#

claustro up

This builds the Docker image (first run only) and starts a sandbox container with your source code mounted at /workspace.

3. Launch Claude Code#

claustro claude

Claude Code starts inside the sandbox with --dangerously-skip-permissions — safe because it’s in a disposable container.

4. Clean up#

claustro burn      # stop and remove container (keeps image)
claustro nuke      # also remove cache volumes

Multiple sandboxes#

claustro up --name api
claustro up --name web
claustro claude api
claustro claude web
claustro ls            # list running sandboxes
