Mozilla Festival 2026
October 28-30 | Recinte Fabra i Coats, Barcelona, Spain
Submissions are open until the end of Sunday, May 24, 2026, wherever you are in the world. This is equivalent to Monday, May 25, 2026 at 2:00 PM Central European Summer Time (CEST).

Mozilla Festival is co-created by its community. More than half the program is led by people like you: technologists, artists, policymakers, activists, and bold thinkers from around the world. Now’s your chance to submit a proposal to lead a session at Mozilla Festival 2026.

This year’s theme is Wilding—It 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.

We are inviting you to take this theme and submit a proposal for a session or experience that shows how your work can help us all embrace Wilding—to restore balance, and cultivate infrastructures rooted in care, mutuality, and collective action.

Mozilla Festival 2026 Community Tracks

Wilding Advocacy: This track explores the limits of traditional advocacy in holding technology systems accountable as power concentrates and resists change. It encourages intergenerational learning and highlights practical solutions for how we can normalize, resource, and upscale alternative, disruptive, and open tools for resilience and resistance, particularly in hypersurveilled environments.

Wilding Knowledge: This track explores how communities are actively developing alternative technologies shaped by their own contexts, needs, and intergenerational lived experiences. It highlights localized, accessible approaches that challenge one-size-fits-all tech models.   Wilding Systems: This track brings together systematic conversations on open source, governance models, platform accountability, and the environmental impact of digital infrastructure. The track looks at how we can move away from centres of control, and towards more accountable alternatives. 

Wilding With Nature: This track explores what it means to reimagine technology as deeply connected to the natural world, focusing on regeneration, energy, and our relationship to land and environment. It challenges extractive models of growth by asking how we can build and resource technologies that work with and in favor of natural systems.  

Wilding Youth: This track is a space for young people (ages 13–17) to explore, build, and shape the internet and technology through hands-on, creative sessions. This track is for beginner-friendly, skill-building workshops alongside youth-led sessions, games, and discussions where young people design and facilitate their own ideas.  

Wilding Creativity: This track invites artists across mediums to interpret and challenge AI, data, and digital power, making complex issues more accessible, sensory and felt. We welcome submissions from artists and collectives proposing interactive installations, film, and multi-media art that sparks dialogue, fosters co-creation, and embodies a more human, regenerative technological future.   

Founders Wilding: This track explores how startups can help “wild” the internet by building alternatives to centralized, extractive platforms through trustworthy AI, privacy-first technologies, and healthier online ecosystems. This space highlights early-stage companies actively developing responsible technologies and the conditions they need to grow and endure. 
 

Developers Wilding: Open source AI is growing in the wild, outside the managed gardens of the hyperscalers and the vendor-locked enterprise stacks. The Developer Track is for founders, principal engineers, safety leads, standards folks, all coming together to figure out together whether what's growing becomes durable, or gets paved over.

How You Can Contribute

Host a session or booth: Lead a thought provoking Talk, run a skill-building Lab, or open up a participatory Forum that gets people co-creating and re-imagining an alternative digital future together. Or, host a booth to showcase your projects, spark conversation, and share resources.

Display your art: Design an art installation that inspires attendees to think about community-led technology in new, creative ways.

We are keen to receive proposals that advance a community-led tech future – one rooted in care, participation, and shared power. You'll need to make an account to access the form.

Submit your proposal by end of day May 24, and join us in Barcelona from October 28-30.

Let’s shape what comes next—together.
