SignUpGenius Is a Form.
Your Community Deserves an Event.
SignUpGenius was designed for slot-based sign-ups: who's bringing potato salad, who's volunteering at 9am vs 11am. It's a great tool for that.
But community events — yoga classes, hiking trips, dinner parties — need RSVPs, waitlists, capacity limits, reminders, and check-in. Who's In is purpose-built for exactly that.

Why Organizers Chose the Right Tool
"I used SignUpGenius for my yoga waitlist but it was the wrong tool. Who's In actually knows what an event is — RSVP, waitlist, check-in, all in one."
Rebecca A.
Yoga Studio Owner
"My community kept seeing ads on the sign-up page. Switched to Who's In and the experience is clean and professional. No ads, ever."
Tom H.
Meetup Organizer
"The WhatsApp integration alone was worth switching. I share event links to our group chat and people RSVP in seconds."
Jess N.
Book Club Host
Frequently Asked Questions
Is Who's In a good SignUpGenius alternative?▼
Yes, for events and RSVPs. Who's In is purpose-built for community events with capacity limits, automatic waitlists, WhatsApp sharing, QR check-in, and Stripe paid ticketing — all free. SignUpGenius is better suited for volunteer sign-ups and slot scheduling, not event management.
Does Who's In show ads to my guests?▼
Never. Who's In is completely ad-free for both organizers and guests on the free plan. SignUpGenius displays ads on their free tier, which can look unprofessional on event pages.
Can Who's In handle the same slot-based sign-ups SignUpGenius does?▼
Who's In is optimized for event RSVPs with a single capacity limit and waitlist, not slot-by-slot scheduling. If you need to coordinate who's bringing what dish or who volunteers at what time, SignUpGenius remains the better tool for that specific use case.
Does Who's In have waitlist management?▼
Yes, automatic waitlist management is built in and free. Set a capacity, and when your event fills up, additional RSVPs join a numbered waitlist. When someone cancels, the next person is automatically promoted and notified — no manual work from you.
What about recurring weekly events in Who's In?▼
Who's In has native recurring event support. Create your weekly yoga class once, set it to repeat, and future events auto-generate. SignUpGenius requires you to manually duplicate events each time.
Can I charge for events using Who's In?▼
Yes. Who's In supports Stripe-powered paid ticketing at a flat 2.7% fee (no per-ticket surcharge). SignUpGenius does not support paid event ticketing.
