Hyperfine is a cross-platform command-line benchmarking tool written in Rust. It runs shell commands multiple times, performs statistical analysis with outlier detection, and supports warmup runs, cache-clearing preparation commands, and parameterized benchmark sweeps.

Use cases

• benchmark shell commands from the terminal
• compare the runtime of two or more CLI programs
• measure command performance with warmup and cold-cache runs
• run parameterized benchmarks varying a value like thread count
• export benchmark results as CSV, JSON, or Markdown
• detect statistical outliers in timing runs

When to choose

• you need statistically sound CLI timing measurements with outlier detection
• you want to compare alternative command-line tools side by side
• you need parameter sweeps of a command across a range of values
• you want a fast, cross-platform benchmarking tool with exportable results

When to avoid

• you need to benchmark HTTP APIs or network services rather than shell commands
• you need GUI application or in-process function benchmarking
• you require profiling with flamegraphs or memory analysis rather than wall-clock timing
