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 4 June 2026; the live site may have changed since.
Calfeed ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: analytics without a consent banner and incomplete email security.
Launched on Product Hunt on June 4, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 3 weeks before launch. We've detected 16 technologies on this site, covering analytics, captcha, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
It's running the same core stack as 6,602 other launches and tighter on security headers than most Product Hunt launches.

Indicative grade from a single automated render, not a substitute for Lighthouse or field data, and not part of the StackScope score.
Vibe Score Breakdown How?

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.
