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

Nudge is partway there, with fast page loads. Main gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on April 20, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 12 weeks before launch. The crawl picked up 12 technologies on this site, covering CDN, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.

For context, it's on one of the most common stacks we track, shared by 2,463 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.
