Best mitmproxy Alternative: Proxyman for macOS
A faster, native, developer-first GUI alternative to mitmproxy
Proxyman is a modern alternative to mitmproxy: a native macOS GUI app with a refined UI/UX and a complete toolset—SSL Proxying, Breakpoints, Map Local/Remote, GraphQL, WebSocket, Scripting, and more.
BETA
Capture more with Network Extension
A transparent proxy for HTTP/HTTPS traffic from apps on your Mac, including apps that ignore the system proxy.
- mitmproxy
- Local capture starts from the command line with mitmproxy --mode local, then you work in a terminal UI or mitmweb.
- Proxyman
- Turn on Network Extension in Settings. Captured requests land in a native Mac app with Map Local, Breakpoint, and Scripting ready to use.
Capture apps that ignore proxy settings
See HTTP/HTTPS requests from Mac apps and scripts that the system proxy misses.
Skip per-app proxy setup
Run tools such as cURL without a --proxy flag or separate proxy settings for each app.
Keep your debugging workflow
Use Map Local, Breakpoint, and Scripting on the requests captured by the extension.
Why mitmproxy Can Be Challenging
While mitmproxy is powerful, it comes with barriers that slow down development workflows
Command Line Only
No GUI interface — everything must be done through terminal commands, making it intimidating for developers who prefer visual tools.
Steep Learning Curve
Built for experts with extensive documentation to master. New users often struggle with complex configuration and scripting requirements.
Complex Setup
Requires manual certificate installation, proxy configuration, and technical knowledge to get basic SSL proxying working properly.
No Visual Debugging
Text-based output makes it hard to quickly analyze requests, compare responses, or spot patterns in network traffic at a glance.
Proxyman solves these issues with a native macOS GUI, easy setup, and intuitive visual debugging

mitmproxy Alternative — FAQs
Is Proxyman a good alternative to mitmproxy?
Yes. Proxyman offers a native macOS GUI with the same core capabilities and thoughtful improvements in usability and performance.
Does Proxyman support core mitmproxy features?
Proxyman includes SSL Proxying, Breakpoints, Map Local/Remote, Block/Allow List, Repeat/Compose, Diff Tool, WebSocket and GraphQL debugging, and more out of the box.
Can I import mitmproxy data?
You can import common formats (HAR, cURL, and more) to replay and analyze traffic captured with other tools.
Does it work with iOS/Android devices and simulators?
Yes. Follow our step-by-step guides for iOS devices, iOS Simulator, Android devices, and Android emulators.
Can Proxyman capture local apps like mitmproxy's local mode?
Yes. Proxyman's Network Extension captures HTTP/HTTPS from Mac apps and scripts that ignore the system proxy. Instead of starting mitmproxy --mode local from the terminal, you turn it on in Settings and debug the traffic in a native Mac app. Network Extension is in beta and requires Proxyman PRO and macOS 26 or later.
Does Proxyman support HTTP/2?
Yes. Proxyman v26.0.0 for macOS captures HTTP/2. Turn on Use HTTP/2 in Settings → General, then inspect each request, response, and trailer, and confirm the negotiated protocol in the Connection Log.

Scripting Tool
Breakpoint, Map local GUI is so slow?
Try Scripting Tool: Use Javascript code to manipulate the Request/Response with your own logic.
We provide a handful of Snippet Code, common Add-ons and JS Libraries to facilitate your debugging procedure and make it 100x faster.
Breakpoint Tool
Breakpoint Tool helps you to modify Requests/Responses Data on the fly without changing any client code. Supports URL, Headers, Body, Status Code, Raw Message, etc.
Map Local Tool
Map Local Tool allows developers to mock a Response with a local file. Boost development speed up by directly modifying the response with Status Code, Header, and Body without waiting for the backend.
GraphQL Debugging
Easily debug GraphQL Request by defining a matching rule with a particular GraphQL QueryName. Works with Breakpoint, Map Local, Map Remote, and Scripting Tool.
WebSocket Realtime
Inspect live WebSocket messages as they arrive. Follow client and server frames in real time, preview their payloads, and quickly track down realtime communication issues.
