Mozilla Festival 2026
October 28 – October 30
Mozilla Festival, aka MozFest, is three days of bold conversations, hands-on building, and ideas worth traveling for. This year, MozFest is taking over Barcelona’s Recinte Fabra i Coats—a former industrial complex turned cultural powerhouse—from Wednesday, October 28 through Friday, October 30, 2026. We are partnering with the City of Barcelona and taking part in Open Tech Week — a city-wide celebration of the people shaping a better digital world.
2026 Theme: Wilding
In a moment when technology feels increasingly centralized, extractive, and controlled, Wilding is a provocation: what happens when we loosen rigid systems and create the conditions for communities and technologies to evolve collectively, naturally, intuitively?
Inspired by ecological practices of rewilding, where gardens and forests are left to regenerate through their own intelligence, this theme explores what it means to let our digital worlds grow wilder, more diverse, and more alive. It means community-owned mesh networks, federated platforms, open protocols, community archives and tools built on transparency, trust and mutual flourishing.
