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

Composer covers some of the launch checklist, with well-configured email security and clean crawl signals. Main gaps: no Permissions-Policy and incomplete legal pages.

Launched on Hacker News on July 27, 2026. The site is served through Cloudflare, with a domain registered in 2003. Our crawler found 13 technologies on this site, covering analytics, payments, APIs, and CDN. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Web Analytics.

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