Stratoscope: SEO and AI Search Checker Built on Next.js A free tool on my website that checks any site the way Google and AI assistants like ChatGPT read it: indexing, titles and markup, speed from real-user data, AI crawler access, security headers and more. Findings are written in plain language, the most important first, each with a way to verify it and how to fix it. Under the hood: safe server-side fetching that blocks requests to private networks, rate limits, email confirmation and a report page by link. I run it before every proposal to show clients concrete issues on their own site.
