The Fedora Design Team hosted the very first Creative Freedom Summit in January 2023. The 3-day event was a wild success, with roughly 635 unique attendees total from 54 countries and up to 265 concurrent live viewers. We used a completely free & open source technology stack, relying on Matrix's element.io service as the central conference home, streaming presentations from Jitsi live to Matrix via PeerTube. In this talk, you will learn how we set up the tech stack for this event, how it went day-to-day for the small volunteer team running it, and our lessons learned for next year's event.
