Luma
Replaceable in one session with an AI coding agent.
Event pages with registration: a page per event, guest list, reminders, calendar invites and optional ticketing, aimed at meetups and small conferences.
Build an event page with registration. STACK - Astro with a Node adapter, SQLite, SES for mail THE PAGE - Title, time in a named zone, location, description, capacity - Show the time in the visitor's zone and say which zone it is; a meetup missed by an hour is the classic failure REGISTRATION - Name and email, double opt-in not required for a free event but a confirmation mail is - Capacity enforced with a unique count inside a transaction, and a waiting list past it THE CALENDAR INVITE - Attach an .ics with a stable UID so an update replaces rather than duplicates - SEQUENCE incremented on every change, or clients ignore the update REMINDERS - One a day before, one an hour before, cancelled by a cancellation Include the schema, the .ics generation and the capacity transaction.
What you lose
- A network where people already look for events, which brings attendance you did not have to find
- Calendar invites and reminders that arrive reliably
- Ticketing with payouts handled
If you would rather not build
- A static page plus a form, which covers most meetups
- Eventbrite, if ticketing matters more than ownership

Why this verdict
our own opinion · changed only by a person
80/100
Verdict yes at 80. The page is easy; the .ics UID and SEQUENCE rules are what make updates work, and almost every home-made version gets them wrong.
