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.
Hexcalibur ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing X-Frame-Options and Content-Security-Policy and no robots.txt.
Launched on Product Hunt on July 15, 2026. The site is hosted on Vercel. Our crawler found 12 technologies on this site, covering analytics, CSS frameworks, DNS providers, and business email. The stack includes Next.js, React, and Tailwind CSS.
It's also running the same core stack as 10,372 other launches and tighter on security headers than most Product Hunt launches.
