Own this Launch?

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

OpenSparrow covers some of the launch checklist, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on July 25, 2026. The site is served through Cloudflare. Our crawler found 8 technologies on this site, covering analytics, CDN, consent tooling, and DNS providers. The stack includes Google, Cloudflare, and Cloudflare DNS.
