Why organizers switch

Your participants aren’t ad inventory

The people signing up for your potluck are parents, neighbors, and volunteers. On SlotsFilled they never see an ad and are never tracked by third parties — on any tier, including free. That’s the founding rule of the product, not a paid upgrade.

Nobody emails you to fix their signup

Every confirmation email carries a private manage link. Participants change their name, switch to another open slot, or cancel on their own — and a cancellation automatically promotes the first person on the waitlist and emails them.

Slot setup takes seconds, not an evening

For conference days and appointment blocks, pick a date, start, end, and duration — the generator creates every slot at once. Item and shift sheets start from ready-made templates you can edit freely.

Common questions

Is SlotsFilled really free?

Yes. The free plan includes 3 active sheets with 40 participants each, automatic reminders, calendar invites, QR codes, CSV export, and print view — with no ads for you or your participants, ever. Paid plans add more sheets, custom questions, and branding control.

Do my participants need to create an account?

No, never. Participants open your link, pick a slot, and enter a name and email. Their confirmation email includes a private manage link they can use to edit, switch slots, or cancel — no account, no password.

How do I move an existing sheet over from SignUpGenius?

Recreate the sheet in the wizard — for time slots, the generator builds a full day of slots in one click — then share the new link with your group. Most sheets take under five minutes to rebuild.

Will my participants see ads?

No. No tier of SlotsFilled shows ads, and participant pages carry no third-party trackers. Your volunteers are people, not ad inventory.

Does it work on phones?

Yes — it's designed phone-first, because most signups happen from a group chat. Every participant flow works one-handed on a phone, and every sheet also prints cleanly for the clipboard.
