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 4 July 2026; the live site may have changed since.
Umbar covers some of the launch checklist, with complete legal pages and a thorough launch checklist. What needs work: missing several security headers, no robots.txt or sitemap, and tracking cookies set before any opt-in.
Launched on Product Hunt on July 4, 2026. The site is hosted on Hostinger, with a domain registered 5 months before launch. Our crawler found 11 technologies on this site, covering ui library, analytics, CSS frameworks, and business email. The stack includes Next.js, React, and Tailwind CSS.
It's also running the same core stack as 243 other launches.
