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 17 June 2026; the live site may have changed since.
htmlbook has the basics covered well, with a thorough launch checklist, well-configured email security, and clean crawl signals. Visible gaps: no Permissions-Policy, incomplete legal pages, and tracking cookies set before any opt-in.
Launched on Product Hunt on June 17, 2026. The site is hosted on Amazon.com in the United States. Our crawler found 16 technologies on this site, covering advertising, social embeds, analytics, and auth. The stack includes Google Sign-In, Next.js, and React.
Notably, it's on one of the most common stacks we track, shared by 7,861 launches and more locked down than the typical Product Hunt launch.
