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

PromptLab looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 18, 2026. The site is hosted on Amazon.com in the Netherlands, with a domain registered in 2024. We've detected 16 technologies on this site, covering analytics, security, seo, and CDN. The stack includes Apollo.io, Cloudflare, and Cloudflare Bot Management.
