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

CodeHarborHub is largely in shape, with complete legal pages, a thorough launch checklist, and fast page loads. Main gaps: missing several security headers and no email security records.

Launched on Product Hunt on June 28, 2026. The site is hosted on Fastly in the United States. The crawl picked up 18 technologies on this site, covering advertising, analytics, javascript library, and CDN. The stack includes Docusaurus, Google AMP, and Google Funding Choices.

For context, it's one of only 33 launches we've crawled running Google AMP.
