I built a Calendly clone called BookMe — a real booking app with a live database, timezone-aware scheduling, and a double-booking guard — in a single sitting using Claude Code. No subscription, no per-seat pricing, and the entire thing is free to copy. In this video you'll watch the full build from an empty folder to a live, working link: the public booking page, the serverless backend, a real database (so bookings survive a refresh and show up for both people), and a private admin dashboard to manage your availability. 🆓 Full code + every prompt used in this build (free)
