Mozilla Festival 2026

Mozilla's flagship festival moves to Barcelona for three days at Fabra i Coats, under the theme Wilding: what happens when rigid digital systems loosen enough for communities and technologies to evolve together. Sessions cover community-owned networks, open protocols, trustworthy AI and tools built on consent rather than capture, run as participatory workshops rather than keynote theatre. Paid ticket, bought through the Mozilla Foundation checkout. Why go: MozFest is the main European gathering of the people building the non-commercial internet, and this is the year it lands in Barcelona. The workshop format means you contribute rather than watch. Best for anyone working on open protocols, digital rights, public-interest technology or trustworthy AI.
