A native, open-source Proxyman alternative for macOS.
If you like the native Mac workflow but want auditable source code, local-first traffic handling, and core debugging tools without a paid unlock, Rockxy is the clearest place to start.
Why developers switch
Most developers looking for a Proxyman alternative are not trying to relearn proxy debugging. They still want the same core workflow: capture traffic, inspect requests, pause flows, replay them, compare results, and export sessions.
The difference is usually what sits around that workflow. Rockxy leans hard into three things: native macOS performance, source visibility, and local-first behavior. It is built with SwiftUI, AppKit, and SwiftNIO, runs on Apple Silicon and Intel, and keeps capture plus analysis on your Mac.
That makes Rockxy a practical fit for teams that care about privacy review, security review, or simply understanding exactly what their debugging tool is doing under the hood.
Where Rockxy is different
Rockxy does not try to win by checking every marketing box. It wins when you care about native UX, source visibility, and a local-first debugging workflow.
| Requirement | Why Rockxy fits |
|---|---|
| Open-source proxy debugger | Rockxy ships under AGPL-3.0, so you can inspect the source, audit the behavior, and build confidence from the code instead of marketing copy. |
| Native macOS workflow | Rockxy is built specifically for macOS with SwiftUI and AppKit, not wrapped in Electron or ported from another platform. |
| All core tools in one app | HTTPS interception, breakpoints, scripting, replay, diff, Map Local, Map Remote, and HAR export are part of the core debugging workflow. |
| Local-first privacy posture | Traffic handling happens on-device. Rockxy does not need cloud accounts, subscriptions, or telemetry to deliver the main product experience. |
| AI-assisted debugging without wrappers | Rockxy includes a built-in MCP server, so Claude Desktop, Cursor, Windsurf, and Zed can inspect captured flows directly through the shipped app. |
What you do not give up
Switching only makes sense if the replacement still handles real day-to-day debugging work.
Traffic capture
Inspect HTTP, HTTPS, WebSocket, and GraphQL-over-HTTP traffic from apps running on your Mac.
Modify and replay
Pause requests, edit them, replay them, and compare results side by side when a bug only shows up after one small header or payload change.
Rules and scripting
Use Map Local, Map Remote, header rewriting, and JavaScript scripting to turn captured traffic into a repeatable debugging environment.
Share and export
Export HAR, cURL, raw HTTP, and native Rockxy sessions when you need to hand a bug off to another engineer or reproduce it later.
