Codeterminals and worktrees

25+agent CLIs supported16panes in parallelRealterminals, not emulated outputLocalkeys never leave the machine
01

One worktree per agent.

Own branch, own terminal, own dev server. Nothing steps on your checkout.

02

Bring the CLI you pay for.

Claude Code, Codex, Gemini, Copilot, Cursor — running as themselves, on your subscription.

03

Nothing is proxied.

Your machine talks to your provider on your key. The account holds a plan, not your work.
