Relay: AI Multi-Agent Automation Platform (Full Source Code)
AI automation platform that chains specialized agents into real workflows, from one task in to a finished result out. Full Node.js source code, zero dependencies.
Try the Live DemoRelay is a full AI multi-agent automation platform, built to chain specialized AI agents into real, repeatable workflows.
Give every agent its own name, role, and focused system prompt: a Researcher, a Copywriter, a Fact-checker, an Editor, whatever the job calls for.
Chain them into a sequential pipeline where each agent's output automatically becomes the next agent's input, and reorder steps any time.
Type a task, hit run, and watch every agent's output stream in step by step, live.
Every run is logged with each agent's exact input and output, so you always know what happened and why.
Start from ready-made templates, a blog pipeline, a customer email pipeline, a research pipeline, and customize from there.
Bring your own key: connect Gemini or Claude with your own API key from Settings. No key yet? Relay still runs on a built-in test engine so you can try everything without one.
