Crawlie – Free open-source SEO audit tool for humans and agents
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.
Crawlie – Free open-source SEO audit tool for humans and agents launched on June 18, 2026 with 20 votes, #853 of 22,647 launches that month and more than 90% of that year's launches.
In plain words
Crawlie is a free, open-source SEO audit tool designed for developers and AI agents building marketing websites. It runs locally, integrates with AI agents via MCP, and audits sites for both traditional search engine optimization and visibility in AI search systems like ChatGPT and Perplexity. Unlike typical paid SEO tools, it provides actionable explanations for each issue found, showing not just what's wrong but how to fix it.

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
