Google Lighthouse is a free, open-source tool that audits a single web page for performance, accessibility, SEO, and best practices. It's built into Chrome DevTools and available via CLI.
How EchoBat Compares to Google Lighthouse
EchoBat integrates Lighthouse directly — you can run Lighthouse audits on any page during a scan. But EchoBat goes far beyond what Lighthouse alone can do: it crawls your entire site, runs 25+ coverage lenses, detects 2,000+ technologies, builds site architecture graphs, and supports AI agent workflows.
When EchoBat Wins
Think of it this way: Lighthouse is a microscope for one page. EchoBat is a radar system for your entire site — and it has Lighthouse built in.
