A free SignUpGenius alternative, without the ads
Updated · By the OpenSignup team
SignUpGenius does the job. But its free plan puts ads on your sign-up pages, and the way to get rid of them is to start paying. OpenSignup is a free alternative that has no ads to begin with, is open-source, and lets people sign up without creating an account.
Why people go looking for a SignUpGenius alternative
The ads
SignUpGenius shows ads on sign-up pages for free accounts. Its cheapest paid plan, Silver, costs $8.99 a month billed annually and removes the ads from one sign-up. (SignUpGenius pricing, checked September 26, 2026) OpenSignup has no ads at all, because there's no ad network in it.
The price
Close behind is paying to remove something that felt like it should have been free. OpenSignup is free to use, and free to self-host if you want full control.
The data
Some organizers would rather their list of parents or volunteers didn't live on a server they can't see. OpenSignup is open-source under AGPL-3.0, so you can self-host it and keep every sign-up on your own hardware.
The friction
With OpenSignup, people sign up by opening a link. No account required.

What OpenSignup handles well
Snack rotations for teams and classrooms. Potlucks and class parties. Volunteer shifts for PTAs, churches, and community groups. Carpools and ride coordination. The kind of small logistics that fill up a school year.
How it works
- Create your sheet. Add the slots (dishes, shifts, dates, seats) in a couple of minutes.
- Share the link by email, text, or group chat.
- People sign up without an account, and everyone can see what's still open.
Switching from SignUpGenius
For a new sign-up, there's nothing to migrate. Build your sheet in OpenSignup, share the new link, and you're done. Participants never needed an account with either tool, so the experience on their end is just as simple, minus the ads.
