Tomorrow's job starts where today's ended: the repo, the agent's history and the project's logins wait on your disk, and a terminal you leave open keeps its database warm. Docker and sudo included. From $39 a month.

When it is the better pick
Cloud agents shine at quick, self-contained tasks launched from the vendor's app. Your Compute takes the jobs that need your services, your tools or a session that lasts for days. Run both on one subscription: quick fixes in the vendor's app, long jobs on detachbox.
Questions about this
Do I pay for the model twice?
No. Claude Code and Codex on detachbox run on the subscriptions you already pay for. Compute costs from $39 a month, every project included.
Why not start a fresh VM every time?
A new VM needs the repo, dependencies and databases set up. On your Compute the repo and agent history are already on disk. A terminal you leave open keeps databases warm for the next job.
Can I watch the agent work?
Yes. It runs in a terminal you open from any browser or your phone, live, with the full scrollback.
