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 10 April 2026; the live site may have changed since.
Data sources scores well across the board, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing Referrer-Policy and Permissions-Policy and tracking cookies set before any opt-in.
Launched on Product Hunt on April 10, 2026. The site is hosted on Cloudflare in the United States, with a domain registered in 2020. We've detected 22 technologies on this site, covering analytics, advertising, seo, and CDN. The stack includes Next.js, React, and Tailwind CSS.
It's on one of the most common stacks we track, shared by 7,863 launches and more locked down than the typical Product Hunt launch.
