    Agent Relay helps software teams work better with coding agents, and helps those agents work better as a team. It gives Claude Code, Codex, OpenCode, and custom agents shared messaging, session history, and access to tools like GitHub, Linear, and Slack. Teams can see what every agent is doing, run checked and resumable workflows, and step in when human judgment is needed. Run it in our cloud, locally, or on your own hardware.
