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

Zfour is largely in shape, with a thorough launch checklist, well-configured email security, and clean crawl signals. What needs work: missing several security headers and placeholder text in the legal pages.

Launched on Product Hunt on April 29, 2026. The site is hosted on WIX_COM in Israel, with a domain registered in 2025. The crawl picked up 18 technologies on this site, covering advertising, seo, AI builders, and analytics. The stack includes Google, React, and Bolt.

For context, it's running the same core stack as 287 other launches.
