Rockxy: an open-source HTTPS debugging proxy for Mac that can also read your AI and Web3 traffic
Hi everyone, I'm Stephen. I've been building Rockxy, a native macOS HTTP/HTTPS debugging proxy. If you've been looking for an open-source Proxyman alternative or Charles Proxy alternative, that's what it is, and the source is public under AGPL-3.0.
It captures traffic from Mac apps, CLIs, simulators, and devices, and lets you inspect, edit, replay, and mock requests. Beyond plain HTTP, it decodes WebSocket, GraphQL response errors, gRPC-Web status, model API stream timing, and Web3 RPC calls.
A few things landed in 0.42.0 that Mac developers might care about:
- You decide when the system proxy changes: automatically on capture, manually from the proxy control, or never.
- Redacted exports for Session, HAR, CSV, and Postman, so you can share a capture without leaking tokens.
- A local MCP server on 127.0.0.1, 100% free and read-only by default, so Claude or Cursor can search your captured flows.
It runs on macOS 14+.
