Score: 7.3/10 (Innovation: 8, Technical: 8, Documentation: 7, Utility: 6)

Sigwire is a live TUI dashboard that streams every Linux signal (e.g., SIGINT, SIGSEGV) across all processes by hooking kernel eBPF tracepoints, showing sender, target, handler timing, and syscall interruptions in real-time. It innovatively combines eBPF for zero-overhead tracing with a rich terminal interface and a kernel-level signal picker, offering deep debug insight into signal-driven behavior for developers.

Target audience: backend devs, systems programmers, devops
