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.
RPLY scores highly overall, with complete legal pages, a thorough launch checklist, and fast page loads. Main gaps: no Content-Security-Policy and incomplete email security.
Launched on Hacker News on April 5, 2026. The site is hosted on Vercel. Our crawler found 15 technologies on this site, covering seo, advertising, 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 10,672 launches and more locked down than the typical Hacker News launch.
