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 25 June 2026; the live site may have changed since.

Prototyper scores well across the board, with complete legal pages, a complete set of security headers, and a thorough launch checklist.

Launched on Hacker News on June 25, 2026. The site is hosted on Amazon.com in the United States. The crawl picked up 13 technologies on this site, covering analytics, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 8,555 launches and more locked down than the typical Hacker News launch.
