Agent Relay is a low-latency messaging and coordination layer for AI agents.
Think: agents that actually talk to each other. In real time. Without rewiring your setup.
Agent Relay is a developer-first protocol and runtime that lets AI agents communicate like a team instead of a bunch of isolated scripts.
If your agent can print to stdout, it can participate.
Right now, most agents:
- Run alone
- Can’t coordinate
- Only "communicate" after they’re done
That’s not how teams work. And agents are teams.
Agent Relay gives them a shared, fast, boring-in-the-best-way communication layer.
- ⚡ Sub-5ms message delivery
- 🔌 Works across providers (Claude, Codex, Gemini, custom)
- 🧠 No config changes to your existing agent setup
- 🖥️ CLI-native — pipes, streams, stdout, not frameworks
No YAML marathons. No SDK lock-in. No magic.
You’ll find:
- Core protocol implementations
- CLIs and SDKs
- Demos and examples
- Weird experiments that might become real features
Some repos are stable. Some are spicy. All are moving.
- Primitives over platforms
- Interop over lock-in
- Fast by default
- If it’s not simple, it’s not done
Agent Relay should fade into the background and just work.
Early. Actively built. Opinions welcome.
APIs will change. That’s the fun part.

Built for agents that shouldn’t have to work alone.
