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 6 June 2026; the live site may have changed since.
Constants covers some of the launch checklist, with a complete set of security headers and a thorough launch checklist. Worth fixing first: incomplete legal pages, no robots.txt or sitemap, and analytics without a consent banner.
Launched on Product Hunt on June 6, 2026. The site is hosted on Amazon.com in the United States. Our crawler found 14 technologies on this site, covering security, advertising, analytics, and CDN. The stack includes Next.js, React, and Tailwind CSS.
Notably, it's running the same core stack as 296 other launches and tighter on security headers than most Product Hunt launches.
