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.

Dewan ETS Calculator looks production-ready overall, with clean crawl signals. Visible gaps: missing Permissions-Policy and Content-Security-Policy, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on June 22, 2026. The site is hosted on Cloudflare in the United States, with a domain registered in 2024. We've detected 11 technologies on this site, covering CDN, DNS providers, business email, and transactional email. The stack includes Next.js, React, and Cloudflare.

It's on one of the most common stacks we track, shared by 511 launches and more locked down than the typical Product Hunt launch.
