hyperfine

Benchmark commands with repeated measurements and exportable comparisons.

hyperfine is a command-line benchmarking tool for comparing programs or command variants. It supports repeated runs with statistical summaries, warmup runs, preparation commands, parameterized benchmarks, and exports in formats including JSON, CSV, and Markdown.

The utility is implemented in Rust and uses Clap for command-line argument handling. It runs on multiple platforms and is dual-licensed under MIT or Apache-2.0.
