Diagnose Slow Page Load Times
Identify the root causes of slow page loads using Lighthouse performance diagnostics and metrics.
Pre-Launch Performance Audit
Run a full Lighthouse audit before launching your site to catch performance, accessibility, and SEO issues.
ToolLaunching a website without a performance audit is like shipping software without running the test suite. Lighthouse measures four critical dimensions -- performance, accessibility, best practices, and SEO -- giving you a comprehensive readiness score before real users start hitting your pages.
ToolRouter's audit_url skill runs a complete Google Lighthouse audit against any URL and returns scores for each category along with specific diagnostics. You get actionable recommendations ranked by impact, so you know exactly what to fix before going live.
This is essential for product launches, marketing site redesigns, and new landing pages. Catching a slow-loading hero image or missing accessibility label before launch is infinitely cheaper than fixing it after users have already bounced.
