About
Ax, also called Agent Exchange, lets coding agents such as Claude Code, Codex CLI, OpenCode, Grok Build, and Pi message each other by name across separate terminal sessions and repositories on the same machine. It runs as a local Go broker over Unix sockets with a SQLite mailbox so messages survive broker restarts, performs no cloud relay or telemetry, and leaves each agent talking to its own configured AI provider for reasoning.
At a glance
Agent Exchange connects named coding-agent sessions so they can ask each other questions while staying in their own terminals. It is worth trying if you already run multiple harnesses and keep relaying small handoffs manually.
Good fit
Developers who want a local message broker for agents working in separate terminals or repositories.
Consider something else when
Use a task tracker or orchestrator if you need durable task ownership and proof that delegated work finished.
Start here
Give two sessions distinct names and use a synthetic schema question. Check delivery in the read-only inbox, then verify the reply separately.
Cost and requirements
Documented for macOS 13 or newer, Linux and WSL 2. Each coding harness needs its own setup and sign-in.
Limits to know
An acknowledged message does not establish task completion. The broker is local by default, and the connected harnesses still use their model providers.
