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 17 June 2026; the live site may have changed since.

Offline PDF Redactor looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and no email security records.

Launched on PeerPush on June 17, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 8 weeks before launch. We've detected 9 technologies on this site, covering CDN, analytics, CSS frameworks, and DNS providers. The stack includes Astro, Tailwind CSS, and Cloudflare.

It's on a stack we've seen on only 13 launches.

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.
