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 16 June 2026; the live site may have changed since.

MCQ Corrector is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.

Launched on Product Hunt on June 16, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 2 weeks before launch. The crawl picked up 8 technologies on this site, covering CDN, DNS providers, business email, and web fonts. The stack includes cdnjs, Cloudflare, and Cloudflare DNS.
