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 5 July 2026; the live site may have changed since.
TuneStems has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and no email security records.
Launched on Product Hunt on July 5, 2026. The site is served through Cloudflare, with a domain registered 1 week before launch. Our crawler found 21 technologies on this site, covering directory, analytics, ui library, and CDN. The stack includes Next.js, React, and Tailwind CSS.
It's also running the same core stack as 3,329 other launches.
