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 June 2026; the live site may have changed since.

ClearSkys ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist.

Launched on Product Hunt on June 25, 2026. The site is hosted on Hetzner Online GmbH in Germany, with a domain registered 5 weeks before launch. We've detected 12 technologies on this site, covering servers, analytics, baas, and DNS providers. The stack includes Caddy, Cloudflare DNS, and Google Search Console.

It's one of 95 launches on this exact stack and tighter on security headers than most Product Hunt launches.
