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

Duck Framework scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing Permissions-Policy and Strict-Transport-Security and incomplete email security.

Launched on PeerPush on April 27, 2026. The site is hosted on Heroku, with a domain registered 5 weeks before launch. We've detected 7 technologies on this site, covering seo, analytics, DNS providers, and business email. The stack includes Bing Webmaster, Google Analytics, and Google Search Console.

It's one of 44 launches on this exact stack and more locked down than the typical PeerPush launch.
