In their own words

Crawlie

Crawlie is a technical SEO and GEO crawler that audits websites and offers guidance on addressing issues. It checks broken links, redirects, missing metadata, and more than 40 SEO and generative-engine issues. Each crawl returns distinct Health, GEO, and Accessibility scores, with output available in the terminal or as JSON, CSV, and shareable HTML reports. JavaScript rendering and structured data audits are supported. The open-source crawler includes an MCP server; the hosted service includes a hosted MCP server and REST API on every plan. Local options include an npm-installed CLI and MCP server, plus a signed macOS DMG for the desktop app. Hosted deploy-triggered crawls are documented for Vercel, alongside GitHub, Netlify, and custom CI hooks. The Free plan is free and includes 200 credits per month, three sites, one seat, and up to 1,000 pages per crawl. Pro is $29 a month; Business is $149 a month. Spronta Ltd makes Crawlie in London, United Kingdom.
