Own this Launch?

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

Criticalwindow ships with the launch fundamentals in place, with a thorough launch checklist and clean crawl signals. What needs work: missing Permissions-Policy and Strict-Transport-Security, incomplete legal pages, and no email security records.

Launched on Hacker News on July 6, 2026. The site is served through Cloudflare. Our crawler found 4 technologies on this site, covering CDN, developer tools, DNS providers, and javascript library. The stack includes Cloudflare, Cloudflare DNS, and Vite.

It's also tighter on security headers than most Hacker News launches.
