__mitmproxy__ is an interactive, SSL-capable man-in-the-middle proxy for HTTP
with a console interface.

__mitmdump__ is the command-line version of mitmproxy. Think tcpdump for HTTP.

__libmproxy__ is the library that mitmproxy and mitmdump are built on.

Documentation, tutorials and distribution packages can be found on the
mitmproxy.org website:  
[mitmproxy.org](http://mitmproxy.org).

Installation Instructions are available at [mitmproxy.org/doc/install.html](http://mitmproxy.org/doc/install.html).

Features
--------

- 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.
- Transparent proxy mode on OSX and Linux.
- Make scripted changes to HTTP traffic using Python.
- SSL certificates for interception are generated on the fly.
- And much, much more.

__mitmproxy__ is tested and developed on OSX, Linux and OpenBSD. On Windows,
only mitmdump is supported, which does not have a graphical user interface.



Hacking
-------

To get started hacking on mitmproxy, make sure you have
[Python](http://www.python.org) 2.7.x. with
[virtualenv](https://virtualenv.pypa.io/en/latest/) installed (you can find
installation instructions for virtualenv
[here](https://virtualenv.pypa.io/en/latest/installation.html)). Then do the
following:

```
$ git clone https://github.com/mitmproxy/mitmproxy.git
$ git clone https://github.com/mitmproxy/netlib.git
$ git clone https://github.com/mitmproxy/pathod.git
$ cd mitmproxy
$ ./dev
```

The *dev* script will create a virtualenv environment in a directory called
"venv.mitmproxy", and install all of mitmproxy's development requirements, plus
all optional modules. The primary mitmproxy components - mitmproxy, netlib and
pathod - are all installed "editable", so any changes to the source in the git
checkouts will be reflected live in the virtualenv.

To confirm that you're up and running, activate the virtualenv, and run the
mitmproxy test suite:

```shell
$ source ../venv.mitmproxy/bin/activate # ..\venv.mitmproxy\Scripts\activate.bat on Windows
$ nosetests ./test
```
Note that the main executables for the project - **mitmdump**, **mitmproxy** and
**mitmweb** - are all created within the virtualenv. After activating the
virtualenv, they will be on your $PATH, and you can run them like any other
command:

```$ mitmdump --version```

For convenience, the project includes an
[autoenv](https://github.com/kennethreitz/autoenv) file
([.env](https://github.com/mitmproxy/mitmproxy/blob/master/.env)) that
auto-activates the virtualenv when you cd into the mitmproxy directory.


### Testing

If you've followed the procedure above, you already have all the development
requirements installed, and you can simply run the test suite:

```nosetests ./test```

Please ensure that all patches are accompanied by matching changes in the test
suite. The project maintains 100% test coverage.


### Docs

Rendering the documentation requires [countershape](http://github.com/cortesi/countershape). After installation, you can render the documentation to the doc like this:

`cshape doc-src doc`
