with rigorous statistical analysis - no signup, no server uploads, everything runs locally in your browser.
Statistical analysis features
KDE Density Plots
Bootstrap CI
Mann-Whitney U
Outlier Detection
- Kernel Density Estimation (KDE) with Silverman bandwidth for visualizing execution time distributions
- Bootstrap confidence intervals (9999 resamples) for robust median estimation
- Mann-Whitney U test with tie correction for rigorous pairwise comparison
- Z-score based outlier removal to clean noisy benchmark runs
- Warmup row stripping to exclude cold-start measurements
Export for academic papers
Export your benchmark ranking table as LaTeX (with booktabs formatting) or Markdown.
Download interactive charts as high-resolution PNG images ready for LaTeX documents, Beamer presentations, or technical reports.
