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 June 2026; the live site may have changed since.

Cortex is missing several launch fundamentals. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 18, 2026. The site is hosted on Amazon.com in the United States. Our crawler found 7 technologies on this site, covering security, auth, CDN, and frameworks. The stack includes Clerk, Next.js, and React.

Notably, it's running the same core stack as 1,583 other launches.
