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 10 April 2026; the live site may have changed since.
CertFlip looks production-ready overall, with a complete set of security headers, a thorough launch checklist, and well-configured email security. What needs work: incomplete legal pages and no sitemap.
Launched on Product Hunt on April 7, 2026. The site is hosted on HETZNER-AS in Germany, with a domain registered 3 days before launch. We've detected 7 technologies on this site, covering CSS frameworks, developer tools, DNS providers, and business email. The stack includes Tailwind CSS, Cloudflare DNS, and Google Fonts.
It's running the same core stack as 5,950 other launches and tighter on security headers than most Product Hunt launches.
