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 16 July 2026; the live site may have changed since.
Pqdsa is largely in shape, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and no email security records.
Launched on Hacker News on July 16, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 2 weeks before launch. The crawl picked up 4 technologies on this site, covering developer tools, DNS providers, web fonts, and servers. The stack includes AWS Route 53, Caddy, and Google Fonts.

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?

| AI typography signals | +15 |
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.
