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

mailfixture ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.

Launched on PeerPush on July 13, 2026. The site is hosted on netcup - netcup GmbH in Austria, with a domain registered 1 week before launch. We've detected 11 technologies on this site, covering analytics, captcha, DNS providers, and business email. The stack includes Ahrefs, Caddy, and Cloudflare DNS.

It's tighter on security headers than most PeerPush launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
