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 18 April 2026; the live site may have changed since.

ExtraBrain is partway there, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on PeerPush on April 18, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered 10 weeks before launch. The crawl picked up 10 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Alpine.js, Tailwind CSS, and Cloudflare DNS.

For context, it's one of just 3 launches we've crawled on this exact stack.

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.
