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 18 July 2026; the live site may have changed since.
DemoBook has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers, tracking cookies set before any opt-in, and no email security records.
Launched on PeerPush on July 18, 2026. The site is hosted on Vercel. Our crawler found 15 technologies on this site, covering analytics, affiliate, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
It's also on one of the most common stacks we track, shared by 10,662 launches.
