A free Rallly alternative, with no accounts
Overlap does what you came to Rallly for — one link, everyone marks when they are free, best time wins — and then puts that time in everyone’s calendar. Nobody signs up for anything.
The difference is what happens after the group agrees. Overlap turns the winning time into a real calendar invitation, sent from the organiser's own calendar with a Meet link, so nobody has to copy the time into a chat and hope.

- Rallly works as a poll where you propose specific times and participants vote on them. It does not offer a freeform grid where everyone paints their full availability. ↩
- Rallly sends calendar invitations when you finalize a poll. The free plan includes Google Meet integration; Pro adds Zoom, Microsoft Teams, and Webex. ↩
- Free plan allows up to 3 open polls at a time with unlimited participants. Polls are deleted 30 days after their dates pass. Pro removes these limits and adds custom branding and advanced features. ↩
When Rallly is the better answer
You want to poll a shortlist of specific times rather than collect open availability, or you want self-hosting (Rallly is open-source).
Why people go looking
The 3-poll limit on the free plan requires closing old polls to make room, and picking specific times to propose is more work than showing a grid and asking everyone when they're free.
What Overlap does with your data
Giving an email address is optional, and an address is only ever used to put you on one calendar invitation. There is no advertising and no cross-site tracking. Everything about an event is deleted automatically 365 days after it is created — see the privacy policy, which names every company that receives anything.
Try it against your next actual meeting
The honest test is a real group, not a demo. Create an event, paste the link in the group chat, and see whether it is less work than what you did last time. If it is not, Rallly is still there.
