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 June 2026; the live site may have changed since.
InstaPDFKit has the basics covered well, with a thorough launch checklist, fast page loads, and clean crawl signals. What needs work: no Permissions-Policy, incomplete legal pages, and no email security records.
Launched on Product Hunt on June 4, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 4 days before launch. Our crawler found 17 technologies on this site, covering analytics, advertising, baas, and build tooling. The stack includes Google Funding Choices, Tailwind CSS, and Vite.
Notably, it's running the same core stack as 1,341 other launches and tighter on security headers than most Product Hunt launches.

Vibe Score Breakdown How?

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.
