SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Rapidly identify and quantify performance regressions in web pages by automating measurements and baseline comparisons across deployments.

Core Features & Use Cases

  • Baseline capture and drift tracking across PRs.
  • Per-page metrics: TTFB, FCP, LCP, DOM Interactive, DOM Complete, Full Load, total requests, transfer size.
  • Diff-based comparisons and trend charts to guide optimizations.

Quick Start

Submit /benchmark with a URL to start a full performance audit and baseline comparison.

FAQPage Schema
How do I detect web page performance regressions across deployments?

To detect web page performance regressions, run repeatable benchmarks that measure metrics like TTFB, FCP, and LCP, then compare current results against a stored baseline file to surface diffs and trends.

What web vitals and load metrics are tracked during a baseline performance audit?

A baseline performance audit tracks TTFB, FCP, LCP, DOM Interactive, DOM Complete, Full Load, total requests, and total resource transfer size to quantify page performance drift.

How do I set up baseline performance tracking for PR reviews?

To set up baseline performance tracking for PR reviews, you need a running browse daemon and a stored baseline file to execute benchmarks and output a structured diff report comparing current metrics against the baseline.

Does benchmarking web vitals require a specific environment to run?

Benchmarking web vitals requires a running browse daemon to execute the performance measurements and a stored baseline file to compare the current results against for detecting regressions.

Can I visualize performance trends and diffs for web page load times?

You can visualize performance trends and diffs for web page load times by running benchmarks that compare current TTFB, FCP, and LCP metrics against stored baselines, generating trend charts to guide optimizations.

What is the best way to automate web page performance measurements?

The best way to automate web page performance measurements is by running repeatable benchmarks that capture core metrics like DOM Interactive and total resource transfer, then comparing results to a stored baseline to identify drift.
