Group sign-ups that are actually a joy to use.
From 2 weeks of high school AP exam proctoring to Friday night football concessions and kindergarten snack duty. Fast, delightful, mobile-first sheets with zero ads and zero forced accounts.
For scheduled slots: Apple/iCal subscribes to the slot schedule; Google Calendar and .ics downloads add a copy. After swaps or cancellations, update your calendar too.
Magic Quick-Fill
This is the actual tool you'll use on the next screen. Describe what you need in plain English, and it builds the slots for you.
Here's what your volunteers would see:
1:00 PM – 1:15 PM Conference
⏰ Thu, Oct 22 • 1 slot left (0/1)
1:15 PM – 1:30 PM Conference
⏰ Thu, Oct 22 • Filled (1/1)
Built for the demands of high schools, booster clubs & athletic leagues
When 300 parents open a concessions link at 7:00 PM, legacy platforms buckle and double-book slots. Signup Giant is engineered for high concurrency and multi-slot institutional scale.

Everything old sign-up tools get wrong, actually fixed
No ads, no participant accounts, and no paywalled exports. Compare the difference below:
Banner ads and sponsored pop-ups cluttering sign-up pages
Zero ads, on every tier, including free — forever. No third-party ad networks, ever.
Ad-removal plans only cover one sign-up sheet at a time
Our free plan covers 3 active sheets ad-free. Need more? One simple pass covers unlimited sheets.
Volunteers forced or nudged to create an account just to claim a spot
No participant accounts, ever. Volunteers just enter their name and email, tap confirm, and they're done.
Can't cancel or swap a spot without emailing the organizer
Every confirmation includes a private magic link so volunteers can cancel or swap in one tap, no login required.
Desktop-style tables that require pinch-zooming on a phone
Every sign-up page is a mobile-first card layout from the start, not a shrunk-down spreadsheet.
CSV exports, waitlists, and branding locked behind paid tiers
All three are free on every plan here, including Free. Paid plans add unlimited active sheets.
A shared signup link needs an extra layer of access control
Add an optional sheet password on any plan, including Free. Share it with your group; participants still need no account.
Two people signing up at the same second and double-booking the same spot
Zero double-bookings, guaranteed. The moment someone claims a spot, it's reserved instantly.
Everyday signup tools and curated themes are free. Upgrade for unlimited sheets.
