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

SyncWhen scores highly overall, with complete legal pages, well-configured email security, and clean crawl signals. Visible gaps: missing Permissions-Policy and Content-Security-Policy.

Launched on PeerPush on May 21, 2026. The domain was registered 12 weeks before launch. We've detected 9 technologies on this site, covering backend framework, CSS frameworks, DNS providers, and email forwarding. The stack includes Tailwind CSS, Vue.js, and Google Search Console.

It's one of only 30 launches we've crawled running Maileroo and more locked down than the typical PeerPush launch.

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.
