Best Doodle alternatives at a glance
| Alternative | Best for | License |
|---|---|---|
| Rallly | Closest group scheduling polls | AGPL-3.0 |
| Cal.diy | Personal booking pages (not for production) | MIT |
| Easy!Appointments | Appointment booking for service businesses | GPL-3.0 |
How we chose these Doodle alternatives
We looked for open-source tools that overlap with Doodle's core: finding a time that works for a group with a poll, and letting people book slots. We verified each project's license, recent activity, stars, and self-hosting in its repository. Doodle is mainly about group polls, so only Rallly matches it closely, and the others lean toward booking. See our methodology for the full criteria.
Important: Cal.diy is not a drop-in replacement for Cal.com
Cal.diy is the open-source community edition of Cal.com, MIT-licensed, with all enterprise and commercial code removed. It lacks teams, organizations, SAML SSO, SCIM, workflow automation, and routing forms, and its README says it is strictly recommended for personal, non-production use. Use Cal.com itself for commercial scheduling.
Easy!Appointments for service businesses
Easy!Appointments is a GPL-3.0 self-hosted appointment scheduler with Google Calendar sync and customizable workflows, suited to healthcare, salons, and other service businesses. Features such as SMS, payment processing, and managed hosting are offered as paid services.

Why look for a Doodle alternative?
Doodle is a proprietary hosted service with ads and limits on its free plan, paid tiers for premium features, and event and participant data stored on its servers. Open-source alternatives let you self-host polls and booking, avoid ads and per-user pricing, and keep scheduling data private, at the cost of running the software yourself.
