Features

Everything you need for local dev

One daemon. Many projects. Zero port conflicts.

Stable Ports

Same port every time. Deterministic assignment from identity hash. No more port roulette.

pd claim myapp:api

Agent Coordination

Sessions, notes, locks, pub/sub messaging. Built for multi-agent dev with Claude, Cursor, and Aider.

DNS Resolution

Access services by name instead of port number. Writes to /etc/hosts for OS-level resolution.
