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 16 August 2026; the live site may have changed since.

C21 Horizon ships with the basics, with a thorough launch checklist, well-configured email security, and clean crawl signals. Main gaps: missing several security headers and incomplete legal pages.

Launched on Product Hunt on August 16, 2026. The site is hosted on Name Hero in the United States, with a domain registered in 2024. We've detected 22 technologies on this site, covering wordpress plugin, javascript library, servers, and analytics. The stack includes Bootstrap, WordPress, and Amazon SES.

It's one of 93 launches on this exact stack.
