Rockxy
What Rockxy is
Rockxy is an open source HTTP/HTTPS debugging proxy for macOS that captures and inspects traffic from apps and devices, then lets developers modify, replay and compare requests. It describes support for WebSocket, GraphQL, AI API and Web3 JSON-RPC traffic as well. Tools include rules, breakpoints, local and remote mapping, header editing, network conditions, response diffs and mocking. Users can filter captured traffic by method, host, status, headers, body, process or full text, then save filters. 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 captured 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 public release requires macOS 14 or later and supports Apple Silicon and Intel Macs. iPhone and iOS Simulator capture requires manual proxy and certificate setup. Plans include a free tier, one-time individual options, a yearly team plan and an Enterprise quote on request.
