Score: 7.5/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 7)

Brr is an eBPF runtime reporter and profiler that unifies bpftop-style metrics with perf-style sampling, allowing users to drill down into source-level hotspots. It is notable for using the perf_event_open API and bpf syscall directly, and for its TUI that maps CPU samples to eBPF program source lines including kernel function call stacks.

Target audience: backend devs, devops, performance engineers, kernel developers
