Performance regressions quietly accumulate across pages and PRs, making it hard to spot slowdowns before they reach users.
Run the benchmark on a target URL to capture baselines and compare current performance.

Capture baselines of page load times and Core Web Vitals, then compare current PR measurements against them. You can run page-specific diffs or quick canary runs for targeted pages to isolate regressions.
Baseline-driven performance regression detection captures initial page load metrics as a reference, then compares subsequent measurements against this baseline to track performance trends and spot slowdowns across PRs over time.
Yes, you need a local environment with Bun and the browse daemon to measure Core Web Vitals. These are required to execute baseline capture, page selection, diff, and trend analysis modes.
Yes, you can run quick canary tests on targeted pages using page selection flags. This allows you to capture page-specific diffs and compare current page load metrics against the baseline without scanning the entire workflow.
The best way to track page load metrics over time is to use trend mode. It compares current measurements against historical baselines across multiple PRs, enabling consistent monitoring of page load times and resource sizes.
