EchoBat — Multi-Engine Site Intelligence Platform

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.

Seven Analysis Engines, One Scan

Every EchoBat scan runs Discovery, Pulse, Crawl, Fingerprint, Render, ArchMap, and Analyze in sequence. Discovery resolves the entry URL, follows canonical signals, and consults the sitemap. Pulse runs Core Web Vitals plus Lighthouse against a representative sample. Crawl walks the full link graph and captures every response. Fingerprint identifies frameworks, CMS platforms, analytics, ad networks, and 400+ technologies. Render executes JavaScript in a headless browser so single-page apps are analysed on the rendered DOM. ArchMap builds the internal-linking and depth model. Analyze runs the 25+ coverage lenses that score every page on SEO, performance, accessibility, security, structured data, and content quality.

Built for Humans and AI Agents

EchoBat is one of the first site-intelligence platforms designed from day one for AI coding agents. The CLI emits structured JSON, accepts token-aware output suffixes so responses fit inside agent context windows, and ships an MCP server so Claude Code, Cursor, Windsurf, and any other Model Context Protocol client can scan a site, propose fixes, apply them, and re-scan in a single closed loop. Humans get a desktop tray app, a cloud portal at echobatseo.com, and white-label PDF reports.

Free Locally, Paid When You Need the Cloud

The desktop engine and CLI are free to use on your own machine. Cloud sync, scheduled scans, team seats, the API, and white-label reports ship with the Standard, Pro, and Whitelabel plans. There is no account required to run a local scan and no page-count limit on the free tier — the paid plans pay for cloud infrastructure, team features, and priority support.
