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

Polynya is early-stage. Main gaps: missing several security headers, incomplete legal pages, and no mobile viewport meta tag.

Launched on Hacker News on April 26, 2026. The site is served through Cloudflare, with a domain registered 1 week before launch. We've detected 3 technologies on this site, covering CDN, DNS providers, and protocol. The stack includes Cloudflare, Cloudflare DNS, and HTTP/3.
