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 30 April 2026; the live site may have changed since.

ClassroomFeed looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on April 30, 2026. The site is hosted on Vercel, with a domain registered 12 months before launch. We've detected 7 technologies on this site, covering transactional email, developer tools, DNS providers, and hosting. The stack includes Google Search Console, HSTS, and Mailgun.

It's on one of the most common stacks we track, shared by 2,956 launches.
