Need your work to stay in the EU? Terminalbox runs in Germany. For everything else, Start runs three terminals with Docker and the limits board where Base runs one without Docker.
Questions about this
Why does Docker matter for an agent?
It lets the agent start the Postgres, Redis and queue your app runs on, right beside the app, and test the whole stack before staging sees it.
Is the isolation the same?
Both run unprivileged system containers on a shared kernel. detachbox turns nesting on so Docker runs inside. Every customer is walled off from the others at the network, and each project gets a home folder of its own.
Can I move my setup over?
Yes. Push your repos, pick a size, clone each one into a project. The agent CLIs are already installed; connect your subscriptions or API keys in the dashboard.
