FAQ

What are the system requirements to run ProxyBoy?

ProxyBoy requires Windows 10 or 11, Node.js 20 or later, and a GitHub Copilot subscription to use the AI assistant features (the proxy engine works without a subscription).

How does ProxyBoy handle HTTPS traffic inspection?

To inspect HTTPS traffic, users must install ProxyBoy's root CA certificate into the Windows certificate store via Settings → Install Certificate. The certificate is generated locally and stored in the user's profile without leaving the machine.

What can the embedded AI assistant do?

The Copilot-powered agent can fetch recent traffic, search flows by URL or headers, find error responses, analyze specific requests, create breakpoint rules, mock API endpoints with local files, export captures as HAR files, and control the proxy engine itself.
