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 July 2026; the live site may have changed since.
ProntoFax looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on July 17, 2026. The site is hosted on AWS S3 and served through AWS CloudFront, with a domain registered 1 week before launch. We've detected 9 technologies on this site, covering analytics, CDN, cloud, and DNS providers. The stack includes Amazon Web Services, AWS CloudFront, and AWS S3.
It's on one of the most common stacks we track, shared by 342 launches.
