We built a real bookings app — sign-in, a calendar, a payments step, and a public page — start to finish, and logged every prompt. This is the unedited build log, not a demo.
The plan
One prompt to scaffold, one to wire auth, one to add the calendar, one to take a payment, one to deploy. Five prompts, thirty minutes, a live URL.
What tripped us up
The calendar’s timezone handling needed a second pass, and the payment webhook wanted a real domain before it would verify. Both were quick fixes once we knew to look for them.
Want the deployed version on your own domain? That’s the next note.
