Performance regression detection by establishing baselines for key web metrics and comparing current results against them to surface regressions early.

Detect web performance regressions by establishing metric baselines and comparing current Core Web Vitals, page load times, and resource sizes against them during PR reviews.
Baseline performance monitoring works by collecting TTFB, FCP, LCP, and DOM metrics via tooling, storing them as baselines, and comparing subsequent test results to identify any regressions.
Yes, you can track bundle size and resource timing trends over time by running periodic baseline audits to generate trend reports that reveal performance shifts across pages.
Yes, collecting page load metrics requires a browse daemon along with baseline storage and tooling to gather resource timings and bundle sizes for accurate trend analysis.
The best way to establish a baseline for page load times is to run a performance audit on a target URL, which captures current metrics to serve as the comparison anchor for future tests.
Your LCP metric shows a performance regression because the current Largest Contentful Paint measurement exceeds the previously established baseline threshold captured during initial monitoring.
