Own this Launch?

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 25 May 2026; the live site may have changed since.

ZephyPhone covers some of the launch checklist, with a complete set of security headers, a thorough launch checklist, and well-configured email security. What needs work: incomplete legal pages and no robots.txt or sitemap.

Launched on Product Hunt on May 25, 2026. The site is hosted on AWS S3 and served through AWS CloudFront, with a domain registered 7 months before launch. Our crawler found 19 technologies on this site, covering analytics, communication, business email, and advertising. The stack includes Google Sign-In, Amazon Web Services, and AWS CloudFront.

It's also running the same core stack as 422 other launches and tighter on security headers than most Product Hunt launches.
