It hooks kernel tracepoints (signal_generate, signal_deliver, rt_sigreturn, sys_exit) rather than ptrace or strace, so it observes all processes simultaneously with no per-process setup and negligible overhead. The UI supports fuzzy filtering, per-signal muting (patching a BPF global live), a detail inspector showing sigaction flags and the target's blocked sigset, and a signal picker modal. Built with a JS userspace layer and a C BPF kernel layer, it requires a BTF-enabled kernel and the yeet daemon for privileged BPF loading. ## Full article daily.dev links to this article rather than hosting it.
