With AgentBox you can coordinate multiple tasks all at once, without juggling windows or terminals: ask a coordinator session (either codex, claude, pi, opencode etc.) to work on each task in a dedicated sandbox.
Since each sandbox is used only for one task, you avoid side effects, and you don't need to manage branches, schema changes, system updates, temporary folders cleanup etc.
Also sandbox costs is minimal, a few $ per month, since each box is used only for the time of a task: if a dedicated hetzner VM is around 8$/mo, using ~100 sandboxes a month for a few hours each is around ~5$/mo (billed by the minute)
