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 29 May 2026; the live site may have changed since.

CliffGuard HENRY tax saving calculator ships with the launch fundamentals in place, with a complete set of security headers, a thorough launch checklist, and well-configured email security. Worth fixing first: incomplete legal pages and tracking cookies set before any opt-in.

Launched on PeerPush on May 29, 2026. The site is served through Cloudflare, with a domain registered 7 weeks before launch. We've detected 15 technologies on this site, covering analytics, business email, ai api, and CDN. The stack includes Next.js, React, and Tailwind CSS.

It's running the same core stack as 3,886 other launches and tighter on security headers than most PeerPush launches.
