Sheetbug is live. It’s the sign-up sheet app I’ve been building since October 22: make a sheet of dates and slots, share one link, and let people claim a spot from their phone without creating an account.
The first release covers the full loop. Organizers can create, preview, publish, and share a sheet, including a downloadable QR code. Participants get a confirmation email with a calendar file and a link to change or cancel their sign-up. Reminders follow before the slot, using the sheet’s time zone.
It’s running as one Next.js service on Railway with Postgres. Resend handles production email, and the reminder and retention jobs run inside the server. That means the service stays awake rather than sleeping between requests.
The deployment needed a couple of checks beyond seeing the homepage load. Registration succeeding didn’t prove email worked, so I confirmed the verification email reached my inbox. I also checked that Railway replaces a visitor-supplied client-IP header with the real address. Otherwise the app’s rate limits could trust an address somebody made up.
The first public version is up. There’s more in the feature queue, but this gets the basic job into people’s hands: ask for help, fill the spots, and remind everyone what they signed up for.
