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

Yak is partway there, with a thorough launch checklist. Worth fixing first: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on April 27, 2026. The site is served through Cloudflare, with a domain registered in 2000. The crawl picked up 4 technologies on this site, covering CDN, CSS frameworks, developer tools, and protocol. The stack includes Tailwind CSS, Cloudflare, and HTTP/3.

For context, it's running the same core stack as 5,950 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.
