Open Developers Conference 2026
A developer-focused open source conference run by the OSPN community behind the Open Source Conference (OSC) series. Billed as an "open source culture festival," it packs seminars, hands-on sessions, and community booths on DevOps, dev tools, and cloud into a single free day. Modest in size at 100-plus attendees, its strength since 2018 has been direct access to the developers behind OSS projects.
