OSI-licensed only · self-hostable
Doodle is a hosted scheduling tool: you propose times, participants vote, and you pick the winner. Open-source alternatives let you run polls on your own server without ads or accounts for participants, and a few cover booking pages too.
Every tool below is under an OSI-approved licence (AGPL-3.0 or GPL-3.0), checked against its repository. Framadate, a popular poll tool, is left out because its repository was archived in 2025 and is no longer maintained.
