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 28 July 2026; the live site may have changed since.
Knowrix scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: tracking cookies set before any opt-in and incomplete email security.
Launched on Product Hunt on July 28, 2026. The site is hosted on Contabo GmbH in Germany, with a domain registered 3 months before launch. Our crawler found 19 technologies on this site, covering advertising, analytics, APIs, and auth. The stack includes Auth.js, Next.js, and React.

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.
Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| AI palette signals | +5 |
| AI writing signals | +5 |
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.
