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 August 2026; the live site may have changed since.

Kadu is missing several launch fundamentals. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on August 18, 2026. The site is served through Cloudflare, with a domain registered 6 months before launch. Our crawler found 3 technologies on this site, covering CDN, javascript library, and package cdn. The stack includes Cloudflare, html5-qrcode, and unpkg.
