Rockxy
What it is
Rockxy is a native macOS proxy for capturing and examining network traffic from apps and devices. It handles HTTP, HTTPS, WebSocket, GraphQL, AI API, and Web3 JSON-RPC traffic, then lets users edit requests and responses, replay calls, apply rules, set breakpoints, map local or remote endpoints, change headers, simulate network conditions, mock responses, and compare response differences. Captured traffic can be searched by method, host, status, headers, body, process, or full text, with saved filters. A local MCP integration works with Claude, ChatGPT, Gemini, Cursor, and GitHub Copilot and is described as free and unlimited across tiers. Rockxy says traffic remains on the Mac, while remote model use requires reviewing context and destination. The HTTPS root certificate key is stored in macOS Keychain, and pinned hosts pass through automatically. The open-source AGPL-3.0 release requires macOS 14 or later on Apple Silicon or Intel. iPhone and iOS Simulator capture requires manual proxy and certificate setup. A free plan is available; paid plans start at $79.
