Open SEO Crawler: Free SEO Crawler, Website Audit & AI Crawler Checker (Self-Hosted)
Open SEO Crawler is a free, open-source SEO crawler you run locally: a self-hosted website SEO crawler and site audit tool that crawls any website for technical SEO issues. Fast, concurrent, and CMS-aware, it's a drop-in alternative to Screaming Frog, Sitebulb, and Ahrefs Site Audit, with no accounts, no API keys, no cloud, and no per-URL limits.
It is also an AI crawler checker. Can AI search and Google read your pages? After each crawl, a sample of pages is requested as Googlebot, Bingbot, Applebot and every AI crawler that publishes its user agent (GPTBot, OAI-SearchBot, ChatGPT-User, PerplexityBot, CCBot). A page that a crawler is blocked from, challenged on, redirected away from or served a thinner version of gets flagged, and so does text that only appears after JavaScript runs. When the crawl is done, the AI brief button packs it into a summary and a ready-made prompt you can paste into any AI assistant.
Your AI assistant can drive it. The repo ships an MCP server and a command-line tool, so Claude Code, Claude Desktop, Cursor and other MCP apps (or any script) can start crawls, read the issues and pull up any page without opening the browser. The crawler still calls no AI: your assistant calls the crawler. Set it up.
Built for SEO professionals, web developers, and site owners who want a real technical SEO audit that stays on their machine. Use it as a free SEO crawler for a single site or a recurring website crawler across your whole portfolio.

How it compares
Companion: SEO Side Panel for Chrome
The crawler covers a whole site. For the one page you have open, there is SEO Side Panel, a free Chrome extension from the same maker. It stays open beside every page you visit and lists each issue with its fix.
