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 19 July 2026; the live site may have changed since.

Guys put QR codes on websites is early-stage. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on July 19, 2026. The site is hosted on netcup-AS - netcup GmbH in Germany. We've detected 4 technologies on this site, covering business email, DNS providers, and servers. The stack includes Migadu, netcup DNS, and netcup Mail.
