benchmark

To detect frontend performance regressions, you can establish baseline page timings and Core Web Vitals, then automatically compare new PR builds against those baselines to flag any degradation when changes are opened or merged.

Measuring Core Web Vitals for historical trend analysis involves collecting real metrics from running pages using perf tooling, allowing you to visualize performance trends and identify drift over time as you ship features.

Baseline comparison for page load latency works by capturing deterministic timing data with a browse daemon, storing those baseline metrics, and generating comparison reports that highlight clear degradation alerts for new builds.

Yes, you can audit per-page resource sizes and timings during automated workflows by running benchmarks against target URLs, which applies deterministic data gathering to satisfy per-page audit requirements.

Yes, you need a browse daemon to collect real frontend metrics from running pages, as it provides the perf tooling required for deterministic data gathering, baseline storage, and comparison reporting.
