benchmark

Detect web performance regressions in a pull request by capturing a baseline and comparing current runs against historical data. The benchmark workflow automates this by running a browse daemon to collect web vitals and alert on regressions.

Baseline-driven performance trend analysis tracks web vitals over time to catch gradual slowdowns. By capturing initial performance metrics and comparing subsequent runs, it identifies regressions and provides actionable optimization insights.

Benchmark a web page to measure Core Web Vitals by running a browse daemon against the target URL. The tool collects multi-page performance profiling data, establishes a baseline, and compares it against historical trends.

You can use Lighthouse metrics for performance regression detection in CI by integrating a benchmark workflow. It captures baseline web vitals data and compares runs against historical trends to alert on regressions.

The best way to monitor web performance without obvious causes is automated baseline capture and trend reporting. A browse daemon continuously measures web vitals to detect regressions before users notice them.

Set up a web performance baseline for trend analysis by running the benchmark on a URL. This initial data collection captures core web vitals, enabling future PR comparisons and regression alerts.
