Lighthouse CI Accessibility Integration

What Is Lighthouse CI?

Lighthouse CI is a suite of tools for running Google Lighthouse audits in CI pipelines. The most common GitHub Actions integration uses treosh/lighthouse-ci-action.

Lighthouse provides:

• Performance, accessibility, best practices, and SEO scoring (0-100)
• Individual audit results with pass/fail status and detailed findings
• Score budgets and assertions to fail builds on regressions
• HTML and JSON report artifacts
• Score comparison across runs for trend tracking

Accessibility focus: The Lighthouse accessibility category runs a subset of axe-core rules and reports a weighted score from 0-100 along with individual audit violations.
