The problem

Developers have no easy way to benchmark how long a shell command takes across multiple runs — time only runs once and hyperfine requires a Rust installation most Node developers don't have.

If you've hit this before, you know how it goes — you either run the command once with time , install hyperfine via brew or cargo, or just eyeball the timing.

As a solution, I created bench-run

Benchmark any shell command with min/max/avg/median timing over N runs

It's zero-dependency Node.js, so you can run it immediately without installing anything:

npx bench-run "npm test" --runs 5

Enter fullscreen mode

Exit fullscreen mode

Output:

bench-run: npm test Runs: 5

Run 1/5... 4.231s Run 2/5... 4.108s Run 3/5... 4.189s Run 4/5... 4.212s Run 5/5...…
