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 20 April 2026; the live site may have changed since.

Redactpdf ships with the basics, with fast page loads and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on April 19, 2026. The site is served through Cloudflare, with a domain registered the day of launch. We've detected 8 technologies on this site, covering advertising, CDN, consent tooling, and DNS providers. The stack includes Google Funding Choices, cdnjs, and Cloudflare.

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.
