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

Sheetbend scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: no Content-Security-Policy and incomplete email security.

Launched on PeerPush on July 15, 2026. The site is hosted on Netlify, with a domain registered 10 weeks before launch. Our crawler found 10 technologies on this site, covering analytics, CSS frameworks, DNS providers, and business email. The stack includes Svelte, SvelteKit, and Tailwind CSS.

It's also the only launch we've crawled on this exact stack 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.
