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 14 July 2026; the live site may have changed since.
ChordSonic ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.
Launched on PeerPush on July 14, 2026. The site is hosted on netcup - netcup GmbH in Austria, with a domain registered 7 weeks before launch. The crawl picked up 11 technologies on this site, covering analytics, CSS frameworks, DNS providers, and email marketing. The stack includes Next.js, React, and Tailwind CSS.
For context, it's running the same core stack as 3,736 other launches and tighter on security headers than most PeerPush launches.
