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

WM Arena still has work before launch. Visible gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Hacker News on April 14, 2026. The site is hosted on OpenNext and served through Cloudflare, with a domain registered 10 weeks before launch. The crawl picked up 5 technologies on this site, covering CDN, frameworks, hosting, and meta-frameworks. The stack includes Next.js, React, and Cloudflare.

For context, it's one of 78 launches on this exact stack.

SignalPoints
AI palette signals +5

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.
