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

Email Posture scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist.

Launched on Product Hunt on July 2, 2026. The site is hosted on IONOS and served through Cloudflare, with a domain registered 2 weeks before launch. We've detected 16 technologies on this site, covering hosting, security, analytics, and auth. The stack includes Clerk, Next.js, and React.

It's the only launch we've crawled on this exact stack and more locked down than the typical Product Hunt launch.
