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 22 July 2026; the live site may have changed since.

Say2PDF is early-stage. Main gaps: no Permissions-Policy, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on July 22, 2026. The site is hosted on Vercel. We've detected 8 technologies on this site, covering analytics, auth, developer tools, and frameworks. The stack includes Capacitor, Google Sign-In, and HSTS.

It's one of just 12 launches we've crawled on this exact stack and more locked down than the typical Product Hunt launch.

SignalPoints
AI palette 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.
