mitmproxy's Introduction

Please note that the master branch of mitmproxy is currently under heavy development. Feel free to test things out, but you may want to use a release.

mitmproxy is an SSL-capable man-in-the-middle proxy for HTTP. It provides a console interface that allows traffic flows to be inspected and edited on the fly.

mitmdump is the command-line version of mitmproxy, with the same functionality but without the frills. Think tcpdump for HTTP.

Both tools are fully documentented in the commandline --help flag, and, in the case of mitmproxy, a built-in help page accessible through the ? keyboard shortcut.

Capabilities

Intercept HTTP requests and responses and modify them on the fly.
Save complete HTTP conversations for later replay and analysis.
Replay the client-side of an HTTP conversations.
Replay HTTP responses of a previously recorded server.
Make scripted changes to HTTP traffic using Python.
SSL certificates for interception are generated on the fly.
