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 13 June 2026; the live site may have changed since.
CertaDoc — Edit PDFs in Browser No Cloud covers some of the launch checklist, with well-configured email security and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and analytics without a consent banner.
Launched on Product Hunt on June 13, 2026. The site is hosted on Google LLC in the United States, with a domain registered 7 weeks before launch. Our crawler found 10 technologies on this site, covering AI builders, analytics, auth, and build tooling. The stack includes Clerk, Tailwind CSS, and Vite.
Notably, it's on one of the most common stacks we track, shared by 262 launches.

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 copy signals | +5 |
| AI writing signals | +5 |
| Recognised AI builder signature | +100 |
| AI asset signals | +10 |
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.
