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 8 June 2026; the live site may have changed since.

cy83rd3ck is missing several launch fundamentals. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 8, 2026. The site is hosted on Fastly in the United States. Our crawler found 5 technologies on this site, covering analytics, CDN, frameworks, and hosting. The stack includes React, Fastly, and GitHub Pages.

Notably, it's one of just 18 launches we've crawled on this exact stack.
