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 July 2026; the live site may have changed since.

Sheeto scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: no Permissions-Policy, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on July 17, 2026. The site is served through Cloudflare, with a domain registered 4 months before launch. The crawl picked up 18 technologies on this site, covering javascript library, analytics, backend framework, and CDN. The stack includes Algolia, Brevo, and Bubble.io.

For context, it's more locked down than the typical Product Hunt launch.

AI code-structure signals +5

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.
