benchmark

Web performance benchmarking captures page load times, Core Web Vitals, and resource sizes to detect regressions. It compares current metrics against a stored baseline to identify slowdowns in web applications.

Compare web performance before and after changes by capturing a performance baseline of page load metrics first. You then run a new analysis to detect regressions and measure the exact impact of your modifications.

Yes, Lighthouse can track long-term web performance trends by running repeated audits over time. This monitors loading metrics and Core Web Vitals continuously to detect gradual regressions across application updates.

Web performance benchmarking supports custom page selection, allowing you to target only the pages affected by your current branch. This focuses the analysis directly on your code changes to detect specific regressions.

To run a quick performance check without a baseline, you need web performance measurement tools like Lighthouse. A single-pass timing check analyzes page load times and Core Web Vitals immediately without requiring prior stored data.
