$ proto

Local & privacy-first

Runs on your machine against the models you host. Point it at a local or self-hosted endpoint and your code, keys, and context never leave your control.

A real agent harness

Sub-agents, teams, skills, hooks, and goal mode, with verification gates and recovery built in, not bolted on.

Lives in your terminal

Reads, writes, and runs code directly in your project. Headless mode and CI-ready for scripted, non-interactive runs.

Speaks every protocol

Drive proto as an ACP coding agent from your editor, or use it as an A2A client to chat with remote agents by name.
