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

Dupr covers some of the launch checklist, with a thorough launch checklist, well-configured email security, and fast page loads. Visible gaps: missing several security headers and incomplete legal pages.

Launched on Hacker News on April 25, 2026. The site is hosted on Netlify and served through Cloudflare. Our crawler found 10 technologies on this site, covering package cdn, ai api, analytics, and CDN. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Web Analytics.

It's also on one of the most common stacks we track, shared by 1,571 launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
