About Agent Relay
Summary
Agent Relay builds coordination infrastructure for teams running multiple AI coding agents in parallel. It gives agents such as Claude Code, Codex, and OpenCode a shared messaging layer, persistent session history, and direct connections to tools like GitHub, Linear, and Slack, replacing the manual work of tracking, handoff, and context-switching across separate agent sessions. Engineering teams get a single plane to monitor every agent, enforce human approval steps, and run resumable multi-agent workflows on cloud, local, or self-hosted infrastructure.
Business model
Deployment options include a hosted cloud service or self-hosted runs, though specific pricing terms are not shown on the site.
Go-to-market
Software engineering teams adopt the product through self-serve access supported by public documentation, targeting developers already running AI coding agents who need to coordinate them at scale.

The infrastructure to run coding agents for your team
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.
