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 29 May 2026; the live site may have changed since.
BlackStack Chrome Extension 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: tracking cookies set before any opt-in and incomplete email security.
Launched on Product Hunt on May 29, 2026. The site is hosted on Vercel. Our crawler found 20 technologies on this site, covering analytics, seo, baas, and chat widgets. The stack includes Next.js, React, and Tailwind CSS.
It's also running the same core stack as 10,661 other launches and tighter on security headers than most Product Hunt launches.
