Benchmark Studio

Interactive JavaScript performance benchmarking in your browser

Statistically Rigorous Performance Comparison

Write JavaScript functions, run them head-to-head, and get results you can trust. Benchmark Studio uses paired t-tests, confidence intervals, and baseline-corrected timing to tell you whether one implementation is genuinely faster than another — not just lucky on one run.
