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 11 July 2026; the live site may have changed since.
Calebar is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers and tracking cookies set before any opt-in.
Launched on Product Hunt on July 11, 2026. The site is hosted on OpenNext and served through Cloudflare, with a domain registered 4 months before launch. The crawl picked up 12 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
For context, it's running the same core stack as 630 other launches.

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.
