Infrastructure for coding agents

Tired of copy/pasting from Claude Code into Slack so your coworker can paste it into their agent?

Ever put an important rule in a skill or AGENTS.md, only for the agent to completely ignore it?

You and your teammates agents ever build the same thing? Wondered whether your coworker's agent made that change intentionally? How many times have you typed "babysit this PR until CI passes"?

Agent Relay is an open-source toolkit for problems like these. It gives engineering teams infrastructure for running coding agents together without replacing the agents and tools they already use.

Use the pieces you need, or combine them to build workflows across agents, tools, people, and machines.

Messaging

Claude/Codex/etc can talk directly through shared channels, threads, DMs, files, search, and real-time events. Agents can run on different machines and still coordinate in the same workspace.

Integrations

GitHub, Linear, Notion, Slack, and other tools are exposed as a virtual filesystem. Agents use ls, cat, grep, and ordinary file writes to work with them.

Shared Sessions

Capture coding agent sessions so your team and their agents can search previous work, decisions, and context.

Agents can search team history through the Shared Sessions plugin, or connect its MCP with agent-relay mcp --sessions-only after Cloud login.

Flows

Turn instructions you hope an agent follows into workflows you can enforce.

Define multi-step workflows in TypeScript with deterministic checks, required steps, and human gates. Put the rules that matter in code instead of relying on a skill or prompt to be remembered and followed.

Learn how write a flow (or lets be honest, show your agent how)

Getting Started

In a project folder, with Node.js 22 or newer:

npx -y agent-relay@next init

Open Claude Code or Codex there, then open a second session in another terminal. Each one joins Relay by itself. Run npx -y agent-relay@next agent list to see their names, then ask one agent to "DM <name> over Agent Relay".

With teammates: one person runs npx -y agent-relay@next init --hosted and shares the init --key line it prints.

More in the getting started guide.

Upgrade: the paid Agent Relay desktop app adds shared sessions and communication across more of your agents.

Self Hosting

Agent Relay has self hosting options for each primitive; start with the self-hosting guide. We're happy to help you set up the whole system on your environment, just reach out to our team hi(at)agentrelay.com and we'll walk you through it.
