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

Sentinel DNS covers some of the launch checklist, with clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on July 26, 2026. The site is served through Cloudflare, with a domain registered 1 week before launch. Our crawler found 13 technologies on this site, covering package cdn, backend framework, CDN, and CSS frameworks. The stack includes Alpine.js, Tailwind CSS, and Chart.js.

It's also running the same core stack as 129 other launches.
