ProxyBoy: Windows HTTP debugging proxy with AI assistant

Key takeaway

A Windows developer has released ProxyBoy, an open-source HTTP/HTTPS debugging proxy with an embedded AI assistant based on GitHub Copilot. The tool lets users intercept, inspect, and modify network traffic while asking an AI agent to analyze patterns, create rules, and export captures—combining manual proxy debugging with conversational AI assistance.

3 Key Points

  • What happened

    A developer has released ProxyBoy, a Windows-native HTTP/HTTPS debugging proxy built with Electron that captures, inspects, and modifies network traffic. It includes an embedded AI assistant powered by the GitHub Copilot SDK that can analyze traffic, create rules, and help debug network issues conversationally.

  • Why it matters

    ProxyBoy fills a gap for Windows users who want a native alternative to tools like Charles Proxy, Fiddler, or Proxyman with AI-powered capabilities built in. The embedded Copilot agent can search traffic, analyze patterns, create breakpoint rules, and export captures without leaving the app, potentially speeding up network debugging workflows.

  • What to watch

    The tool is described as a personal/experimental project rather than production-ready, and it requires a GitHub Copilot subscription for the AI assistant features (the proxy itself works without it). It is Windows 10/11 only, requires Node.js 20+, and is open-source under the MIT license; the creator recommends Proxyman for production use cases.

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.
