The terminal built for agents.

Tabs organized by project, notifications when an agent finishes its task, an AI-powered diff viewer, and the option to quickly move a project into a VM that runs faster than your macOS filesystem.

Pick CPU, RAM and agents; cloud-init does the rest. The first VM of a config is captured as a scrubbed golden image — every later one clones it instantly.

/// BENCHMARKS

Faster inside the VM than outside it.

Agent workloads on ext4 skip the APFS metadata tax and per-spawn Gatekeeper checks — the two things that make agentic coding 10–15× slower on macOS.
