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 June 2026; the live site may have changed since.

Puzzlelair ships with the launch fundamentals in place, with a thorough launch checklist and clean crawl signals. What needs work: missing Permissions-Policy and Content-Security-Policy, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Hacker News on June 22, 2026. The site is hosted on N6 Cloud inc. in the United States, with a domain registered 4 weeks before launch. We've detected 10 technologies on this site, covering analytics, CSS frameworks, developer tools, and DNS providers. The stack includes Rails, Tailwind CSS, and Brevo.

It's one of 66 launches on this exact stack and tighter on security headers than most Hacker News launches.
