eBPF Summit 2025: Hackathon Edition

A global open source hackathon to build, explore, and contribute with eBPF.

About the Hackathon

eBPF Summit: Hackathon Edition invites developers, tinkerers, and open source enthusiasts from all backgrounds to get hands-on with this cutting-edge kernel technology that's being used to build the future of cloud native networking, observability, and security.

Connecting Contributors

The hackathon brings together eBPF developers, operators, advocates, and first-time contributors from around the world — to collaborate, build, and learn from each other.

Building in the Open

From early ideas to production-ready tools, this event is about making progress in public — with support, feedback, and community energy.

Expanding Use Cases

Explore how eBPF powers the next generation of security, networking, and observability — and help push its boundaries by trying new integrations, policies, and workflows.

About eBPF Summit

Since 2020, eBPF Summit has gathered the eBPF community together for a virtual summit that explores and celebrates the open source eBPF ecosystem. With everything from deep dives to hands-on challenges, eBPF Summit brings together everyone building, using, or interested in using eBPF as a platform. This year we're doing something different by hosting this eBPF Hackathon!
