Performance regression detection across changes using the browse daemon. It establishes baselines for page load times, Core Web Vitals, and resource sizes, and compares results before/after changes to surface regressions.
Run the benchmark on a URL to capture a baseline or compare current results against the baseline.

To detect web performance regressions across pull requests, you can capture baseline metrics for page load times and Core Web Vitals, then compare current results against that baseline to surface changes. This requires the browse daemon and a local JSON store under .gstack/benchmark-reports.
For baseline performance analysis, you can collect TTFB, FCP, LCP, DOMInteractive, and DOMComplete events. The benchmark also gathers resource and bundle size data to provide a comprehensive view of page-level performance regressions.
You can compare performance metrics between diff branches by running the benchmark on a URL to capture current results, which are then compared against the saved baseline JSON store under .gstack/benchmark-reports to surface regressions across deployments.
Yes, you need the browse daemon to measure page load times and resource sizes. It is required to establish baselines for Core Web Vitals and bundle data, and to save and view the resulting reports locally in .gstack/benchmark-reports.
Yes, you can track historical performance trends for multiple routes. The benchmark saves reports locally in .gstack/benchmark-reports, allowing you to analyze trend data across historical benchmarks and surface performance changes over time.
