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 June 2026; the live site may have changed since.

Uscrovis has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on June 27, 2026. The site is hosted on Cloudflare in the United States. Our crawler found 11 technologies on this site, covering javascript library, analytics, baas, and CDN. The stack includes cdnjs, Cloudflare, and Cloudflare DNS.

Notably, it's on one of the most common stacks we track, shared by 365 launches.
