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 27 June 2026; the live site may have changed since.
PDF Elf is largely in shape, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and no email security records.
Launched on Product Hunt on June 27, 2026. The site is hosted on Alibaba (US) Technology Co. in the United States. The crawl picked up 7 technologies on this site, covering backend framework, developer tools, DNS providers, and frameworks. The stack includes Vue.js, Alibaba Cloud, and Express.
For context, it's running the same core stack as 200 other 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 |
|---|---|
| Placeholder branding | +10 |
| AI writing signals | +5 |
| AI iconography 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.
