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

PayFlow Engine is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers, no mobile viewport meta tag, and tracking cookies set before any opt-in.

Launched on PeerPush on April 7, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 8 months before launch. The crawl picked up 5 technologies on this site, covering analytics, DNS providers, transactional email, and os. The stack includes Amazon SES, AWS Route 53, and Google Analytics.
