Pure-Python Git implementation
Python C Other

Build Status

This is the Dulwich project.

It aims to provide an interface to git repos (both local and remote) that doesn't call out to git directly but instead uses pure Python.

Homepage: Author: Jelmer Vernooij

The project is named after the part of London that Mr. and Mrs. Git live in in the particular Monty Python sketch.


By default, Dulwich' will attempt to build and install the optional C extensions. The reason for this is that they significantly improve the performance since some low-level operations that are executed often are much slower in CPython.

If you don't want to install the C bindings, specify the --pure argument to

$ python --pure install

or if you are installing from pip:

$ pip install dulwich --global-option="--pure"

Further documentation

The dulwich documentation can be found in doc/ and on the web:

The API reference can be generated using pydoctor, by running "make pydoctor", or on the web:


There is a #dulwich IRC channel on Freenode, and a dulwich mailing list at


The process of porting to Python3 is ongoing. At the moment most of Dulwich runs on Python3, with the exception of some of dulwich.patch and some of the C git compatibility tetsts. Relevant tests are currently being skipped on Python 3, and the full testsuite passing is not an indication that the port is complete.

Something went wrong with that request. Please try again.
