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 13 April 2026; the live site may have changed since.

CodeFluency ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.

Launched on Product Hunt on April 1, 2026. The site is hosted on Railway and served through Cloudflare. We've detected 13 technologies on this site, covering analytics, backend framework, CDN, and developer tools. The stack includes htmx, Cloudflare, and Cloudflare DNS.

It's on a stack we've seen on only 3 launches and tighter on security headers than most Product Hunt launches.
