What Rockxy is
Rockxy is an open-source debugging proxy for macOS that captures and inspects app and device traffic, then lets users modify, replay, and compare requests. It describes support for HTTP, HTTPS, WebSocket, GraphQL, AI API, and Web3 JSON-RPC traffic. Tools include rules, breakpoints, local and remote mapping, header editing, network conditions, response diffs, and mocking. Captured traffic can be filtered by method, host, status, headers, body, process, or full text, and filters can be saved. Its local MCP integration works with Claude, ChatGPT, Gemini, Cursor, and GitHub Copilot, and is described as free and unlimited across tiers. The site says traffic stays on the Mac and is not silently sent to an AI provider; remote model use requires reviewing the selected context and destination. The HTTPS root certificate private key is stored in the macOS Keychain, and pinned hosts pass through automatically. The current release requires macOS 14 or later and supports Apple Silicon and Intel Macs. iPhone and iOS Simulator capture use manual proxy and certificate setup. A free plan is available; paid plans include one-time individual options and a team subscription.
