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 user interface. Think tcpdump for HTTP.
Complete documentation and a set of practical tutorials is included in the distribution package, and is also available at mitmproxy.org.
- 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.
- Reverse proxy mode to forward traffic to a specified server.
- Make scripted changes to HTTP traffic using Python.
- SSL certificates for interception are generated on the fly.

The following auxiliary components may be needed if you plan to hack on mitmproxy:
- The test suite uses the nose unit testing framework and requires human_curl and pathod.
- Rendering the documentation requires countershape.
mitmproxy is tested and developed on OSX, Linux and OpenBSD. Windows is not supported at the moment.
You should also make sure that your console environment is set up with the following:
- EDITOR environment variable to determine the external editor.
- PAGER environment variable to determine the external pager.
- Appropriate entries in your mailcap files to determine external viewers for request and response contents.
