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

DevPrep.app covers some of the launch checklist. What needs work: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on July 12, 2026. The site is hosted on Microsoft Corporation in the United Kingdom, with a domain registered 3 months before launch. Our crawler found 8 technologies on this site, covering developer tools, DNS providers, email forwarding, and web fonts. The stack includes Cloudflare DNS, Cloudflare Email Routing, and Google Fonts.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
