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 10 August 2026; the live site may have changed since.

ZizkaDB is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers.

Launched on Product Hunt on August 10, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 8 months before launch. The crawl picked up 4 technologies on this site, covering frameworks, meta-frameworks, os, and servers. The stack includes Next.js, React, and nginx.

For context, it's running the same core stack as 1,000 other launches.
