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

StableJack scores well across the board, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers and tracking cookies set before any opt-in.

Launched on Product Hunt on June 19, 2026. The site is hosted on Amazon.com in the Netherlands. The crawl picked up 10 technologies on this site, covering business email, analytics, DNS providers, and transactional email. The stack includes Cloudflare DNS, Framer, and GoDaddy Email.
