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 April 2026; the live site may have changed since.
PrepLoop ships with the basics, with complete legal pages. What needs work: missing several security headers, no robots.txt or sitemap, and incomplete email security.
Launched on Product Hunt on April 20, 2026. The site is hosted on Vercel. We've detected 7 technologies on this site, covering CSS frameworks, developer tools, DNS providers, and email forwarding. The stack includes Tailwind CSS, Cloudflare DNS, and Cloudflare Email Routing.
It's running the same core stack as 2,460 other launches.
