crawlie

A fast, free, open-source technical SEO and GEO crawler built for humans and agents. It crawls for broken links, redirects, missing metadata and more than 40 SEO and generative-engine checks, with plain-English guidance on every fix. Each crawl returns three separate scores: Health for technical SEO, GEO for AI-search readiness and Accessibility for WCAG conformance. It runs locally with a CLI and an MCP server, and it can also be reached through a hosted cloud MCP with no install, a Claude Code plugin and skills that work with any agent. A CI mode fails a pipeline on errors to block regressions, a polished shareable HTML report can be generated in one command, and AI-generated sites can be audited. A desktop app is available.
