MozFest 2026: Save the Date

October 28-30, 2026 | Barcelona, Spain

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're still shaping what 2026 will look like—and yes, that means you'll have a say. A theme is coming. The call for proposals is coming. Tickets are coming soon too.

A Festival co-created with community

How to Mozfest

Most festivals hand you a program. We build ours with community.

People from around the world propose the sessions, host the conversations, and shape what MozFest becomes each year. That means the program stays close to what's actually happening on the ground—what you're working on, worried about, and ready to change.

You don't just attend. We co-build together.

Thank you for an incredible Mozilla Festival 2025

For 15 years, Mozilla Festival has been the home for big ideas, bold conversations, and the movement for a better internet.

The world’s most curious and creative minds gather for three days of workshops, debates, and hands-on collaboration to reimagine the role of technology in our lives.

This is your space to think differently, act boldly, and unlearn the internet as you know it.
