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 16 June 2026; the live site may have changed since.

ChordGen covers some of the launch checklist, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 16, 2026. The site is hosted on Amazon.com in the United States. Our crawler found 12 technologies on this site, covering security, auth, CDN, and CSS frameworks. The stack includes Clerk, Next.js, and React.

Notably, it's running the same core stack as 7,716 other launches.
