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.

Code Harbor 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 no email security records.

Launched on Product Hunt on June 17, 2026. The site is hosted on Amazon.com in the United States. Our crawler found 6 technologies on this site, covering DNS providers, frameworks, hosting, and meta-frameworks. The stack includes Next.js, React, and Cloudflare DNS.

Notably, it's running the same core stack as 1,569 other launches.
