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 14 April 2026; the live site may have changed since.

HeyGen CLI has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers and tracking cookies set before any opt-in.

Launched on Product Hunt on April 14, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered in 2015. Our crawler found 13 technologies on this site, covering analytics, security, auth, and CDN. The stack includes Google Sign-In, Next.js, and React.

It's also running the same core stack as 10,661 other launches.
