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 July 2026; the live site may have changed since.
Hearken ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers and incomplete email security.
Launched on Product Hunt on July 6, 2026. The site is served through Cloudflare. Our crawler found 6 technologies on this site, covering CDN, CSS frameworks, DNS providers, and email forwarding. The stack includes Next.js, React, and Tailwind CSS.
It's also running the same core stack as 3,358 other launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
