Nine harnesses. One click.

Every install rewrites the config file the agent expects, keeps a checksummed backup, and hands you a rollback if the probe call fails.

The local /v1 surface.

An OpenAI-compatible listener, on your loopback. Any client that speaks the wire format talks to it as if it were the real thing. Streams pass through. Tool calls pass through. Costs stay yours.

# ANTHROPIC_BASE_URL, OPENAI_API_BASE — same host, both surfaces.
# Yes, that's just 127.0.0.1. We know.

— how it works

Three moves. About five minutes.

— 01

Buy a CDK.

One code, up to two Macs. Transfer between machines from settings — no seat management, no re-purchase.

— 02

Activate on your Mac.

Paste the email and CDK into the app. Unlocks the full harness pack and the /v1 surface.

— 03

Connect any agent.

Pick a harness, hit Install. The config write is atomic and reversible; rollback is one click.

— pricing

One CDK, two shapes.
Both one-time. No auto-renewal.

Claude Code stays free forever. Everything else lives behind one CDK. Pick the shape that matches how you use the app — freeze it at today's build, or roll with a year of updates.
