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 10 July 2026; the live site may have changed since.

Resultant scores highly overall, with a thorough launch checklist, fast page loads, and clean crawl signals. Main gaps: no Strict-Transport-Security, incomplete legal pages, and no email security records.

Launched on Hacker News on July 10, 2026. The site is served through Cloudflare, with a domain registered 3 weeks before launch. Our crawler found 6 technologies on this site, covering analytics, CDN, DNS providers, and web fonts. The stack includes Bing Webmaster, Cloudflare, and Cloudflare DNS.

It's also more locked down than the typical Hacker News launch.
