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 25 August 2026; the live site may have changed since.

Cinderella ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing Content-Security-Policy and Strict-Transport-Security.

Launched on Hacker News on August 25, 2026. The site is hosted on Render and served through Cloudflare, with a domain registered 2 weeks before launch. Our crawler found 11 technologies on this site, covering analytics, auth, CDN, and DNS providers. The stack includes Auth.js, Next.js, and React.

It's also one of 35 launches on this exact stack and tighter on security headers than most Hacker News launches.
