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 21 June 2026; the live site may have changed since.
RectoPDF is largely in shape, with well-configured email security and clean crawl signals. What needs work: no Content-Security-Policy and incomplete legal pages.
Launched on Product Hunt on June 21, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 5 days before launch. The crawl picked up 10 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Astro, Tailwind CSS, and Cloudflare.
For context, it's running the same core stack as 279 other launches and tighter on security headers than most Product Hunt 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.
