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

calcdocu.com has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and incomplete email security.

Launched on Product Hunt on June 17, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 9 weeks before launch. Our crawler found 14 technologies on this site, covering directory, servers, CDN, and CMS. The stack includes WordPress, Cloudflare, and Cloudflare DNS.

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