Own this Launch?

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 5 August 2026; the live site may have changed since.

PDF Extractor ships with the basics, 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 Product Hunt on August 5, 2026. The site is served through Cloudflare, with a domain registered the day of launch. We've detected 7 technologies on this site, covering CDN, DNS providers, frameworks, and meta-frameworks. The stack includes Next.js, React, and Caddy.
