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

Duckle ships with the basics, with a thorough launch checklist, well-configured email security, and clean crawl signals. Visible gaps: missing several security headers and incomplete legal pages.

Launched on Product Hunt on June 18, 2026. The site is hosted on Fastly in the United States. We've detected 4 technologies on this site, covering CDN, DNS providers, web fonts, and hosting. The stack includes Fastly, GitHub Pages, and Google Fonts.

It's on one of the most common stacks we track, shared by 1,161 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.
