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.
PrompTessor scores well across the board, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: no Strict-Transport-Security, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on June 16, 2026. The site is hosted on Hostinger International Limited in Lithuania, with a domain registered in 2025. Our crawler found 23 technologies on this site, covering directory, transactional email, analytics, and auth. The stack includes Auth.js, Next.js, and React.
Notably, it's one of only 45 launches we've crawled running Elastic Email and more locked down than the typical Product Hunt launch.
