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 17 June 2026; the live site may have changed since.
ShieldFive 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 16, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 11 months before launch. Our crawler found 17 technologies on this site, covering business email, baas, captcha, and CDN. The stack includes Next.js, React, and Tailwind CSS.
Notably, it's on one of the most common stacks we track, shared by 7,717 launches and more locked down than the typical Product Hunt launch.
