    Overview

    In this course, we're building Relay, a complete AI workflow automation platform from scratch.

    You'll build the n8n-style canvas with React Flow — triggers, action nodes, and an Agent node that takes over a real Chrome browser in the cloud (Browserbase + Stagehand) to click, scroll, and figure out each step on its own. Give it a goal like "configure a Porsche 911 and email me the link" and watch it happen.

    Every run executes as a durable background job with Trigger.dev, streaming live status back to the canvas node by node — and because it's a real browser session, you can replay exactly what the agent saw and did. Nothing is a black box.

    The canvas is fully multiplayer with Liveblocks: live cursors, names, and avatars. Auth, organizations, and billing run on Clerk; workflows persist to Postgres with Drizzle and Neon; emails send through Resend; Sentry catches what breaks. By the end, you'll deploy the whole thing to production.
