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

Whosbuilt is missing several launch fundamentals. Visible gaps: missing several security headers, incomplete legal pages, and no mobile viewport meta tag.

Launched on Hacker News on July 4, 2026. The site is hosted on Hetzner Online GmbH in Germany, with a domain registered 11 weeks before launch. Our crawler found 3 technologies on this site, covering DNS providers, seo, and servers. The stack includes Caddy, Cloudflare DNS, and Google Search Console.
