Join us for DevDay Exchange Community Hackathon: Berlin, hosted by Max Jendrall, your local OpenAI Codex Ambassador in Berlin!
Build something useful with Codex and ChatGPT alongside Berlin's developers, students, founders and go-to-market builders.
This community-led hackathon is a chance to explore ideas and tools from DevDay, exchange practical workflows and find collaborators ahead of Berlin's official DevDay Exchange and maybe get a chance to win a ticket to the DevDay Exchange on the 26th.
Saturday, 24 October 2026 · 10:00-18:00 CEST.
