Screenshot of ZTools

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 April 2026; the live site may have changed since.

ZTools is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on April 6, 2026. The site is served through Fastly. The crawl picked up 10 technologies on this site, covering analytics, CDN, developer tools, and web fonts. The stack includes Fastly, Google Analytics, and Google Fonts.
