EchoBat is a site intelligence platform that runs seven specialized engines on every scan: Discovery, Pulse, Crawl, Fingerprint, Render, ArchMap, and Analyze. Each engine builds on the previous stage to surface findings that single-pass crawlers miss — tech stack fingerprints, JavaScript-rendered content, Core Web Vitals, Lighthouse audits, broken-link mapping, and 25+ coverage lenses across SEO, performance, accessibility, and security.
