Score: 7.0/10 (Innovation: 6, Technical: 8, Documentation: 7, Utility: 7)

Hyper-DERP is a high-performance drop-in replacement for Tailscale's DERP relay server, written in C++23 with io_uring for 2-10x throughput gains and 40% lower tail latency. It uses kernel TLS offloading to minimize userspace overhead, making it an impressive optimization of a critical networking component.

Target audience: backend devs, devops, network engineers
