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

Zutor scores highly overall, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing Permissions-Policy and Content-Security-Policy and incomplete email security.

Launched on PeerPush on May 23, 2026. The site is hosted on SERVEREL-AS in the United States, with a domain registered 12 weeks before launch. Our crawler found 9 technologies on this site, covering transactional email, developer tools, DNS providers, and email forwarding. The stack includes Amazon SES, Google Fonts, and Google Search Console.

It's also more locked down than the typical PeerPush launch.
