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

Coup de Tête ships with the launch fundamentals in place, with complete legal pages and clean crawl signals. Worth fixing first: no Content-Security-Policy and incomplete email security.

Launched on PeerPush on June 10, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 5 weeks before launch. Our crawler found 10 technologies on this site, covering CSS frameworks, DNS providers, business email, and error tracking. The stack includes Next.js, React, and Tailwind CSS.

Notably, it's running the same core stack as 7,154 other launches and tighter on security headers than most PeerPush launches.
