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 16 July 2026; the live site may have changed since.

Zro covers some of the launch checklist, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing several security headers, no robots.txt or sitemap, and tracking cookies set before any opt-in.

Launched on Product Hunt on July 16, 2026. The site is served through Cloudflare, with a domain registered in 2025. Our crawler found 14 technologies on this site, covering analytics, auth, CDN, and CSS frameworks. The stack includes Clerk, Next.js, and React.

It's also running the same core stack as 3,808 other launches.
