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 4 August 2026; the live site may have changed since.
Zync scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: incomplete email security.
Launched on Product Hunt on August 4, 2026. The site is served through Cloudflare, with a domain registered 5 months before launch. We've detected 19 technologies on this site, covering ai api, analytics, APIs, and baas. The stack includes Google, Anthropic, and Cloudflare.
It's more locked down than the typical Product Hunt launch.

Readiness Breakdown How?
Performance How?
Indicative grade from a single automated render, not a substitute for Lighthouse or field data, and not part of the StackScope score.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
