AI Crawler Access Checker

I built AI Crawler Access Checker, a free tool that helps website owners understand whether AI search engines and crawlers can access their content. It checks GPTBot, ClaudeBot, PerplexityBot and 11 other AI crawlers, analyzing robots.txt rules, HTTP responses, noindex directives, firewalls, and llms.txt. Built with JavaScript, Node.js, and Express, with server-side checks, rate limiting, and security protections. Try it for free and see how accessible your website is to AI crawlers.
