OmniOpenCon 2026

​The third edition of OmniOpenCon is happening between 16 and 17 October 2026!

OmniOpenCon is a gathering of people, projects and communities involved in all things open: open source, open data, open science, open hardware, open education. We value openness, freedom and sharing and we want to bring together all who share these beliefs.

​OmniOpenCon is free as in free speech and as in free beer: everyone is welcome to attend for free, and all information and resources are publicly available. We follow the example and the spirit of FOSDEM.
