SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Performance regression detection uses the browse daemon to establish baselines for page load times, Core Web Vitals, and resource sizes, enabling teams to spot subtle regressions early.

Core Features & Use Cases

  • Baseline capture and per-page comparison across PRs.
  • Automated trend analysis and regression/warning reporting.
  • Artifact generation for CI and stakeholder reviews.

Quick Start

Run /benchmark https://example.com to start a full performance audit and baseline comparison.

FAQPage Schema
How do I detect web performance regressions across pull requests?▼

Detect performance regressions by collecting Core Web Vitals like TTFB, FCP, and LCP via a browse daemon. The tool compares current results against established baselines to identify regressions and optimization opportunities across pull requests.

Can I automate Core Web Vitals baseline capture for CI pipelines?▼

Automate Core Web Vitals baseline capture using the gstack benchmarking workflow to generate per-page reports and artifacts. These outputs integrate into CI pipelines to alert teams about subtle page load regressions during code reviews.

What is automated performance baseline comparison and how does it work?▼

Automated performance baseline comparison evaluates current page speed against historical data. By collecting metrics like LCP and resource sizes via a browse daemon, it identifies deviations, generates trend analysis, and reports regressions.

Does performance benchmarking work without external dependencies?▼

Performance benchmarking works without external dependencies by using an internal browse daemon. It measures target URLs directly to capture Core Web Vitals, compare against baselines, and generate stakeholder review artifacts independently.

When do I need to run a page speed benchmark on a target URL?▼

Run a page speed benchmark on a target URL when you need to establish performance baselines before major changes. It identifies subtle Core Web Vitals regressions early by comparing current page load metrics against historical trends.
