Best open-source Event ticketing & RSVP
The best self-hosted events split in the c17.io catalog is pretix for a ticket shop (the published Eventbrite path — AGPLv3 with additional terms that restrict offering pretix as SaaS to third parties), Mobilizon or Gancio for a Meetup-shaped community agenda, and Indico when the job is a CERN-shaped conference timetable. A meeting poll stays on /best/scheduling-booking.
