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 4 June 2026; the live site may have changed since.
EmailGuard scores well across the board, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: incomplete email security.
Launched on Product Hunt on June 4, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 2 weeks before launch. We've detected 15 technologies on this site, covering payments, security, auth, and captcha. The stack includes Clerk, Next.js, and React.
It's on one of the most common stacks we track, shared by 6,603 launches and more locked down than the typical Product Hunt launch.
