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 25 July 2026; the live site may have changed since.

Cygnus is missing several launch fundamentals. Visible gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Hacker News on July 25, 2026. The site is served through Cloudflare, with a domain registered 1 week before launch. Our crawler found 4 technologies on this site, covering CDN, DNS providers, frameworks, and meta-frameworks. The stack includes Svelte, SvelteKit, and Cloudflare.

It's also one of 53 launches on this exact stack.

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.
