When it is the better pick
Terminalbox runs in Germany. If your work must stay in an EU region, that counts for more than Docker. Otherwise, the box does more for less.
Questions about this
Why does Docker matter for an agent?
Agents test against databases, queues and caches. Without Docker they test against mocks, and the bugs wait for staging.
Is the isolation the same?
Both run unprivileged system containers on a shared kernel. detachbox turns nesting on so Docker runs inside, and walls each box off from its neighbours at the network.
Can I move my setup over?
Push your repos, start a box, clone them. Your agent CLIs are already installed; connect your subscriptions in the dashboard.
