About EchoBat

EchoBat is a multi-engine site-intelligence platform built for technical SEOs, performance engineers, agencies, and AI coding agents. Seven analysis engines (Discovery, Pulse, Crawl, Fingerprint, Render, ArchMap, Analyze) run on every scan and feed 25+ coverage lenses that score every page on SEO, performance, accessibility, security, structured data, and content quality. The CLI emits machine-readable JSON and the MCP server lets AI agents like Claude Code, Cursor, and Windsurf drive scans end-to-end. The desktop tray app keeps the engine warm in the background; the cloud portal at echobatseo.com stores history, scheduling, team seats, and shareable client reports.

Get started by downloading EchoBat for Windows, macOS, or Linux, or choose a paid plan if you need cloud sync, scheduled scans, and team features. Browse the full feature catalogue for what each engine and lens checks, or read the documentation for installation, configuration, and the public API.
