How it works
Simple enough for one-off events. Solid enough for busy sign-up windows.
Create your sheet
Add a title, event timezone, slots, capacity, optional comments, and open or close times.
Share the link
Publish once, then send a clean public link to parents, volunteers, attendees, or customers.
Watch it fill
Participants claim slots without an account while organizers see live capacity updates.
Features
Practical tools for sign-ups that need to stay accurate.
SignupFlow focuses on the parts that make public sign-up sheets reliable: clean sharing, capacity control, participant privacy, and organizer-friendly exports.
No participant accounts
People sign up with a name and email. No passwords, invites, or account setup for guests.
Live slot availability
Capacity changes are broadcast in real time so busy sign-up windows stay accurate.
Self-service changes
Access links let participants find and manage their registrations without exposing private tokens.
Exports that travel
Download CSV for check-in and reporting, or share calendar-ready .ics files.
Time zone aware
Slots are stored in UTC and shown in the event's local timezone, keeping schedules sane.
Public-form protection
Honeypot checks, Turnstile, and rate limits help reduce spam on public registration pages.
Use cases
When a spreadsheet is too manual and a booking system is too much.
Good for short-lived coordination where people need to pick a spot, avoid duplicates, and move on with their day.
