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

Iron Karnet workout app for Apple Watch ships with the basics, with a thorough launch checklist. What needs work: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on July 16, 2026. The site is served through Cloudflare, with a domain registered 3 months before launch. We've detected 3 technologies on this site, covering CDN, DNS providers, and email forwarding. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Email Routing.
