You can detect web performance regressions by running automated benchmarks against target pages to capture baselines and compare current runs. This generates JSON and Markdown reports with clear regression and warning indicators for PR review.
Web performance benchmarks capture Core Web Vitals and key metrics including TTFB, FCP, LCP, DOM timings, and resource bundle sizes. These metrics establish baselines to flag regressions across multiple routes and environments.
Yes, automated benchmarks support ongoing performance monitoring across multiple routes, assets, and environments. They record baselines for page load times and resource sizes, then validate current runs against those baselines.
The best way to compare web performance is running automated benchmarks that measure current page metrics against recorded baselines. This produces detailed reports with regression indicators and recommended next steps for review.
Web performance benchmark reports are generated in both JSON and Markdown formats. These reports include key metrics like TTFB, FCP, LCP, DOM timings, bundle sizes, and recommended next steps for review.
