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 22 June 2026; the live site may have changed since.

Baserates is early-stage. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on June 22, 2026. The site is hosted on Amazon.com in the United States, with a domain registered the day of launch. We've detected 8 technologies on this site, covering CSS frameworks, databases, DNS providers, and email forwarding. The stack includes Next.js, React, and Tailwind CSS.

It's running the same core stack as 8,282 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.
