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.
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!
