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 15 July 2026; the live site may have changed since.

Age Difference Calculator ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: no email security records.

Launched on Product Hunt on July 15, 2026. The site is hosted on Vercel. Our crawler found 9 technologies on this site, covering seo, analytics, DNS providers, and frameworks. The stack includes Next.js, React, and Bing Webmaster.

It's also running the same core stack as 2,210 other launches and tighter on security headers than most Product Hunt launches.
