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

Shunbox scores well across the board, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: no email security records.

Launched on Hacker News on June 7, 2026. The site is hosted on Render in the United States, with a domain registered 5 weeks before launch. We've detected 9 technologies on this site, covering advertising, CDN, DNS providers, and hosting. The stack includes Cloudflare, Facebook, and Facebook Pixel.

It's on one of the most common stacks we track, shared by 141 launches and more locked down than the typical Hacker News launch.
