Own this Launch?

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 22 April 2026; the live site may have changed since.

Ckourse covers some of the launch checklist, with a thorough launch checklist, fast page loads, and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on April 22, 2026. The site is hosted on Contabo in the United States, with a domain registered 6 weeks before launch. Our crawler found 9 technologies on this site, covering analytics, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Caddy, and Google Fonts.

It's also running the same core stack as 5,948 other launches.
