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 10 May 2026; the live site may have changed since.

Hexdocs is largely in shape, with complete legal pages and fast page loads. Main gaps: missing Permissions-Policy and Content-Security-Policy, no robots.txt, and no email security records.

Launched on Hacker News on May 10, 2026. The site is hosted on Fastly in the United States, with a domain registered in 2014. The crawl picked up 6 technologies on this site, covering DNS providers, documentation, business email, and identity. The stack includes Cloudflare DNS, Google Search Console, and Google Workspace.

For context, it's more locked down than the typical Hacker News launch.
