StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 6 July 2026; the live site may have changed since.

Claude Certified Architect — Prep Course is missing several launch fundamentals. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on July 6, 2026. The site is hosted on GitHub Pages and served through Fastly. Our crawler found 5 technologies on this site, covering CDN, frameworks, hosting, and package cdn. The stack includes React, Fastly, and GitHub Pages.

It's also one of just 21 launches we've crawled on this exact stack.
