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 22 April 2026; the live site may have changed since.
OpenWhistle ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: no Content-Security-Policy and incomplete email security.
Launched on Product Hunt on April 22, 2026. The site is hosted on ATSAT Autonomous System in France. We've detected 8 technologies on this site, covering CSS frameworks, DNS providers, transactional email, and frameworks. The stack includes Next.js, React, and Tailwind CSS.
It's running the same core stack as 3,879 other launches and tighter on security headers than most Product Hunt launches.
