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 20 June 2026; the live site may have changed since.

mailplus ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: incomplete email security.

Launched on Product Hunt on June 20, 2026. The site is hosted on Amazon.com in the United States. Our crawler found 9 technologies on this site, covering AI builders, analytics, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Google Analytics, and Google Search Console.

Notably, it's running the same core stack as 1,945 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.
