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 22 June 2026; the live site may have changed since.

ZeroDrop has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers and incomplete email security.

Launched on Hacker News on June 22, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 3 weeks before launch. Our crawler found 9 technologies on this site, covering CDN, DNS providers, email forwarding, and frameworks. The stack includes Next.js, React, and Cloudflare.

Notably, it's running the same core stack as 1,679 other launches.
