Sign-up sheets that just work.
Potlucks, volunteer shifts, class snacks, team schedules, meetings. Make a sheet in a minute, share one link, and watch the slots fill up. Nobody needs an account or an app.

How it works
Create
Pick a template or start blank. Add slots like "Dessert × 3" or "Saturday 9 to 11 am × 2 helpers".
Share
Send one link by WhatsApp, email or text. People open it on any phone or computer.
Done
Everyone picks a slot and types their name. Full slots close automatically, so nothing gets double-booked.

An empty sheet for anything else.
Why people use ClaimASlot
Nothing to sign up for
No accounts and no passwords, not for you and not for your guests. That's why people actually fill it in.
Made for phones
Most people sign up from a group chat. Every page is fast and easy on a small screen.
Private by design
Sheets are hidden from search engines, you choose whether names are public, and everything is deleted automatically after your event. We never sell data.
Free
Unlimited sheets, slots and sign-ups. No trial, no "upgrade to see who signed up". A few small ads pay for the upkeep.
Questions
Is it really free?
Yes. Creating sheets and signing up is free and unlimited. We pay for the upkeep of the site with a few small, clearly marked ads. No pop-ups, and nothing that gets in the way of your sheet.
Do my guests need an account or an app?
No. They open your link in any browser, pick a slot and type their name. That's it.
How do I edit my sheet later?
When you create a sheet you get a private organizer link. Open it to edit slots, see everyone, remove people, close sign-ups or delete the sheet. We also remember it on the device you used.
What if I lose my organizer link?
Check "Your sheets" on this page on the device where you created it. Because we don't use accounts or know who you are, we can't send a lost link to you, so save it somewhere safe.
Can people change or cancel their sign-up?
Yes. Their device remembers the sign-up so they can remove it with one tap, and they get a private link to change it from another device.
Who can see the names?
You decide. By default everyone with the link can see who signed up for what (handy for potlucks). Turn it off and guests only see how many spots are left; you always see all names.
How long is my sheet kept?
Until 30 days after the last date on the sheet (or 180 days after your last edit if it has no dates). Then it's deleted automatically. You can delete it yourself at any time.
