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 28 July 2026; the live site may have changed since.
Cercle has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, no robots.txt or sitemap, and tracking cookies set before any opt-in.
Launched on Product Hunt on July 28, 2026. The site is served through Fastly. Our crawler found 12 technologies on this site, covering analytics, baas, CDN, and DNS providers. The stack includes Apple App Store, Fastly, and Firebase.
