Runs commands repeatedly with warmup, statistical summary (mean/stddev/min/max), export to Markdown/CSV/JSON, and parameter sweeps (`-P`). Cross-platform. The default answer for comparing two CLIs fairly.","theCatch":"It benchmarks *process wall time*, not flamegraphs or allocator profiles — pair with a profiler when the hot path is inside one long process. Shell overhead and cold caches still skew naive runs; read the warmup flags. Not a load-test / HTTP soak tool.","verdict":"MIT/Apache-2.0 CLI bench.
