The 2025 developer program has sold out

Each year, we give free tickets for our events to the most active developers and open source contributors in the Web Summit network.

Our developer initiative is now at capacity. General attendee tickets are still available.

Book tickets for 2025

What’s happening?

Our developer program is all about giving back to active members of the open source developer community. If selected for the program, you can attend any of the talks, masterclasses, roundtables and networking sessions at Web Summit Rio – all for free.

What happens when I apply?

Your application will be reviewed

Our AI system will review each applicant’s contribution, giving priority to frequent contributors to high-impact, open-source projects.

Successful applicants receive a code

If you are one of the chosen applicants, we will issue you with a unique ticket code that can be used to redeem your free Web Summit Rio ticket.

A crowd of seated people. The focus is on one person who is smiling, looking upwards – seemingly at a stage – and clapping.

Redeem your code

Now all that’s left to do is redeem your ticket and join us at Web Summit Rio. We’ll see you in April!

A person (Mozilla chief innovation officer Katharina Borchert) sits next to the armrest on a couch. Their right leg is crossed over their left. Their right hand is resting in their lap and they're gesturing with their left hand. They're looking towards an audience, which is out of shot. They're wearing a headset mic and appear to be speaking. The Web Summit logo is visible on the wall behind them.

“Open source is the best way to get people’s brilliance out there.”

– Katharina Borchert, Chief Innovation Officer, Mozilla

A person (Thoughtworks C.T.O Rebecca Parsons) stands in front of a wall that features the Web Summit Rio logo in several places. They're pictured from the waist up. Their left arm is hanging by their side. In their right hand, which is raised beside their face, they're holding a presentation clicker. They're wearing a headset mic and appear to be speaking.

“Advances in tech bring good, bad and OK things.”

– Rebecca Parsons, CTO, Thoughtworks

A person (Dfinity founder Dominic Williams) pictured from the waist up. They are gesturing with both hands. A presentation clicker is held in the right hand. They are wearing a headset mic and appear to be speaking.

– Dominic Williams, Founder, Dfinity
