Requirements

Optional packages for extended content decoding:

mitmproxy is tested and developed on OSX, Linux and OpenBSD. Windows is not officially supported at the moment.

Hacking

The following components are needed if you plan to hack on mitmproxy:

  • The test suite uses the nose unit testing framework and requires pathod and flask.
  • Rendering the documentation requires countershape.

For convenience, all dependencies save countershape can be installed from pypi to a virtualenv with 'pip install -r requirements.txt'.

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