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 11 April 2026; the live site may have changed since.
PassFlow AI is largely in shape, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.
Launched on Product Hunt on April 10, 2026. The site is hosted on Firebase Hosting and served through Fastly. The crawl picked up 9 technologies on this site, covering analytics, advertising, baas, and CDN. The stack includes Fastly, Firebase, and Firebase Hosting.
For context, it's on one of the most common stacks we track, shared by 107 launches.
