mitmproxy is an interactive, SSL/TLS-capable intercepting proxy for HTTP/1, HTTP/2, HTTP/3, and WebSockets, offered as a console tool (mitmproxy), a web UI (mitmweb), and a command-line dumper (mitmdump). It supports on-the-fly traffic inspection and modification, replay, transparent/reverse/local capture modes, and scripting via a Python addon API.

Use cases

• intercept and inspect https traffic from any app or device
• debug http requests and responses like chrome devtools for native apps
• modify web traffic on the fly with python scripts
• replay recorded http conversations for testing
• man-in-the-middle proxy for penetration testing
• capture local application traffic without proxy settings
• convert captured traffic to openapi specs

When to choose

• you need to inspect, modify, or replay TLS-protected HTTP/WebSocket traffic
• you want scriptable traffic manipulation via a Python API
• you need cross-platform interception including transparent, reverse, and local capture modes
• you want a free open-source alternative to Charles Proxy or Fiddler

When to avoid

• you only need simple non-TLS packet capture (tcpdump or Wireshark may suffice)
• you need a pure load-testing tool rather than interactive interception
• you require interception of non-HTTP protocols without TLS or custom binary protocols out of the box
