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

Satblocks is early-stage. Main gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Hacker News on June 14, 2026. The site is hosted on Cloudflare in the United States, with a domain registered the day of launch. We've detected 3 technologies on this site, covering CDN, DNS providers, and protocol. The stack includes Cloudflare, Cloudflare DNS, and HTTP/3.
