A native macOS GUI alternative to mitmproxy.
mitmproxy is excellent for terminal-first proxy work. Rockxy is for developers who want the same MITM debugging category in a native Mac interface with inspectors, filters, replay, scripting, and local AI assistant access through MCP.
Quick answer
mitmproxy is scriptable, open source, and strong for CLI-centered debugging. Rockxy is better suited when the user wants a native macOS interface, visual inspectors, persistent sessions, and a workflow that feels closer to a desktop debugger.
Rockxy keeps the local-first posture developers expect from a debugging proxy while adding native Mac UI and a first-party MCP bridge for AI-assisted traffic inspection.
Where Rockxy fits
Use Rockxy when you want a MITM proxy that is visual, Mac-native, and ready for app/API debugging without living in a terminal.
Native visual debugger

Still developer-shaped
Use breakpoints, Map Local, Map Remote, JavaScript scripting, replay, and exports when you need control.
AI bridge
The built-in MCP server lets compatible assistants summarize, inspect, replay, and diff captured local flows.
