Description
With AI, it's faster than ever to ship a marketing site... but most of what gets generated is slop that was never built to be found. Plus the tools meant to catch that fall short: most SEO auditors cost money, don't play nicely with your agents, or tell you what's wrong without telling you how to actually rank for SEO and GEO (Generative Engine Optimization: being cited by AI search like ChatGPT, Perplexity, and Google AI Overviews).crawlie fixes that! It's 100% free, it's local-first, it's agent-native (MCP baked in!), and every issue it finds comes with why it matters and how to fix it.
