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

Prosperian looks production-ready overall, with a thorough launch checklist and clean crawl signals. Main gaps: no Content-Security-Policy, incomplete legal pages, and incomplete email security.

Launched on PeerPush on June 30, 2026. The site is hosted on Vercel. We've detected 13 technologies on this site, covering ui library, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.

It's on one of the most common stacks we track, shared by 8,976 launches and more locked down than the typical PeerPush launch.
