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 June 2026; the live site may have changed since.

Rocket Languages looks production-ready overall, 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 30, 2026. The site is hosted on Hostinger and served through Cloudflare, with a domain registered 2 weeks before launch. We've detected 8 technologies on this site, covering CDN, DNS providers, email forwarding, and web fonts. The stack includes Cloudflare, Cloudflare DNS, and Google Fonts.

It's running the same core stack as 734 other launches.
