Overview
mitmproxy provides terminal, web, and non-interactive interfaces for capturing, inspecting, replaying, and modifying HTTP(S), HTTP/2, and WebSocket flows, including Python addons for automation.
Features and best fit
Based on official documentation; not hands-on tested · Content checked:
Key features
Capture, filter, and replay requests and responses
mitmproxy, mitmweb, and mitmdump expose flows for inspection, filtering, saving, replay, and automated Python addon processing.
Sources: [1]
Best fit
Fits API, browser, and mobile debugging plus authorized security tests
Point a client at a local proxy to inspect headers, cookies, TLS behavior, and WebSocket messages while reproducing integration or protocol issues.

Before adoption
Treat TLS interception authority and CA keys as sensitive
Decryption requires clients to trust a mitmproxy CA. Never intercept third-party traffic, protect credentials and personal data in captures, and remove test trust settings afterward.

Supplemental curator note
Use it only on traffic you own or are explicitly authorized to test, and protect the generated CA key and captured data as sensitive material.
Try it in 3 steps
- 1
Create an isolated virtual environment
Isolate the proxy and its dependencies.
python3 -m venv mitm-demo && . mitm-demo/bin/activate - 2
Install the reviewed release
Pin the package to the reviewed version.
python -m pip install "mitmproxy==12.2.3" - 3
Inspect version and options before listening
Verify the CLI and options without capturing traffic.
mitmproxy --version && mitmdump --options | head -40
