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

J-sey Data API covers some of the launch checklist, with a thorough launch checklist, well-configured email security, and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on July 14, 2026. The site is served through Cloudflare. Our crawler found 9 technologies on this site, covering advertising, analytics, CDN, and DNS providers. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Email Routing.
