The terminal built for agents.

A native macOS terminal with a project sidebar. Every chat is a real shell, and agents can run in an isolated Linux VM that's faster than your Mac's own filesystem.

Agentic terminal
Projects and chats, not tabs. Each chat is a real shell in its project directory — run claude, codex, or anything else, side by side.
▣
Isolated & accelerated
One lightweight Linux VM per project: agents can’t touch your Mac, and filesystem-heavy work (installs, clones, cleans) runs dramatically faster.
◉
Notifications & agent status
Live spinner while an agent works, a dot when it finishes, and a native macOS notification the moment it needs you.
⇄
Automatic port forwarding
Dev servers inside the VM show up on localhost automatically — port chips in the sidebar, one click to open, one to stop.

Why the VM?

On macOS
—syspolicyd assesses every fresh executable and script
—APFS pays a metadata tax on every tiny file — brutal at node_modules scale
—agents run with access to your whole disk
▣ In the Vetro VM
+no Gatekeeper in the hot path, filesystem built for tiny files — CPU still native via Apple Virtualization
+fully isolated — agents can touch nothing outside the project
+sparse disk: grows as files are written, hands space back on delete
