Pre-Launch Performance Audit
Run a full Lighthouse audit before launching your site to catch performance, accessibility, and SEO issues.
Check Accessibility Compliance
Audit your pages for WCAG accessibility issues using Lighthouse to ensure your site works for all users.
ToolWeb accessibility is not optional -- it is a legal requirement in many jurisdictions and affects roughly 15% of the global population who live with some form of disability. Beyond compliance, accessible sites tend to perform better in search rankings and provide better experiences for all users, including those on mobile or slow connections.
Lighthouse tests against a subset of WCAG 2.1 guidelines and flags issues like missing alt text, insufficient color contrast, missing form labels, incorrect ARIA attributes, and keyboard navigation problems. Each issue includes the affected element, the specific guideline violated, and how to fix it.
Running accessibility audits regularly -- especially after design changes or new feature launches -- prevents accessibility debt from accumulating. Fixing issues incrementally is far easier than remediating an entire site at once.
