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 9 August 2026; the live site may have changed since.

Matrix Lab has the basics covered well, with clean crawl signals. What needs work: missing Permissions-Policy and Strict-Transport-Security, incomplete legal pages, and no email security records.

Launched on Product Hunt on August 9, 2026. The site is served through Cloudflare, with a domain registered 1 week before launch. Our crawler found 3 technologies on this site, covering CDN, DNS providers, and seo. The stack includes Cloudflare, Cloudflare DNS, and Google Search Console.

It's also tighter on security headers than most Product Hunt launches.
