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 28 July 2026; the live site may have changed since.
Hardbook has the basics covered well, with complete legal pages, well-configured email security, and clean crawl signals. Visible gaps: missing several security headers.
Launched on Product Hunt on July 28, 2026. The site is hosted on Vercel, with a domain registered 3 months before launch. Our crawler found 10 technologies on this site, covering seo, analytics, DNS providers, and business email. The stack includes Next.js, React, and Apple Business Connect.
