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 16 July 2026; the live site may have changed since.
Playsheet 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 PeerPush on July 16, 2026. The site is served through Cloudflare, with a domain registered 5 months before launch. Our crawler found 15 technologies on this site, covering javascript library, analytics, CDN, and developer tools. The stack includes Brevo, Cloudflare, and Cloudflare DNS.
It's also more locked down than the typical PeerPush launch.
