Our verdict on ProxyBoy

ProxyBoy is an open-source Windows desktop HTTP/HTTPS debugging proxy built with Electron. It is aimed at developers who need to capture, inspect, and modify network traffic through a man-in-the-middle proxy. The product covers request and response headers, bodies, timing, and metadata, while automatic SSL certificate generation supports HTTPS traffic inspection. Its free plan and Windows focus make it particularly relevant to Windows users seeking a no-cost proxy with AI assistance.

Its strongest trait is the breadth of debugging controls in one desktop tool. Breakpoint rules can pause and edit requests or responses, while local and remote mapping rules support response mocking and request forwarding. Upstream HTTP and SOCKS5 proxy chaining extends its fit for routed traffic workflows. ProxyBoy also handles WebSocket and Server-Sent Events inspection, HAR import and export, and network throttling with preset or custom profiles. The embedded GitHub Copilot-powered assistant adds traffic search, request analysis, rule creation, and data export.

The main tradeoff is scope. ProxyBoy is Windows-only, so it does not fit teams that need a cross-platform desktop proxy. The project is also described as personal and experimental, which makes its positioning different from a mature, broadly supported enterprise tool. Verified replay is not part of the listed feature set, limiting its fit for workflows centered on replaying captured requests. Choose ProxyBoy if Windows compatibility, open-source access, traffic manipulation, mocking, protocol inspection, and AI-assisted analysis are the priorities. Choose another proxy if cross-platform availability, verified replay, or a more established project posture matters more.
