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

MP4Cat is partway there, with clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on July 20, 2026. The site is served through Cloudflare, with a domain registered 6 weeks before launch. The crawl picked up 5 technologies on this site, covering CDN, DNS providers, email forwarding, and protocol. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Email Routing.
