Can I test my localhost website for accessibility and security?

Yes. CodeFrog is a desktop app that can access any URL your computer can reach — localhost, staging servers, sites behind VPNs, and internal tools. This is CodeFrog's strongest differentiator compared to cloud-based tools like Ahrefs, Semrush, and WAVE, which all require publicly accessible URLs.

Catch accessibility, security, SEO, and HTML errors during development — before they ever reach production.
