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 23 July 2026; the live site may have changed since.
Codex Build Arena covers some of the launch checklist, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and no email security records.
Launched on Product Hunt on July 23, 2026. The site is hosted on GitHub Pages and served through Fastly. Our crawler found 2 technologies on this site, covering CDN and hosting. The stack includes Fastly and GitHub Pages.
It's also running the same core stack as 1,892 other launches.

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.
