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 9 July 2026; the live site may have changed since.

NoteTube ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: incomplete email security.

Launched on Product Hunt on July 9, 2026. The site is hosted on Firebase App Hosting, with a domain registered in 2025. Our crawler found 36 technologies on this site, covering ai api, analytics, advertising, and hosting. The stack includes Google, Next.js, and React.

It's also running the same core stack as 101 other launches and tighter on security headers than most Product Hunt launches.
