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 2 August 2026; the live site may have changed since.
GrowthRail 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 incomplete email security.
Launched on Product Hunt on August 2, 2026. The site is hosted on IONOS SE in the United States, with a domain registered 5 months before launch. Our crawler found 12 technologies on this site, covering analytics, javascript library, 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 4,516 launches.
