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 August 2026; the live site may have changed since.
CofounderFit has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on PeerPush on August 20, 2026. The site is hosted on Vercel, with a domain registered 10 months before launch. Our crawler found 16 technologies on this site, covering analytics, affiliate, baas, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.
It's also running the same core stack as 13,623 other launches.
