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 8 May 2026; the live site may have changed since.

EmailShield 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 incomplete email security.

Launched on Product Hunt on May 8, 2026. The site is hosted on Netlify and served through Cloudflare. Our crawler found 13 technologies on this site, covering security, CDN, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Beehiiv, and Cloudflare.

It's also running the same core stack as 640 other launches.
