stackless / Download


Downloads for older versions of Stackless Python can be found on the archived downloads page.

Source Code

If for some reason, you are not able to obtain the source code from the appropriate branch in the Mercurial repository, you can download it directly from here:



If you use the marvellous Python distribution Anaconda or Miniconda you can install Stackless-Python from the anaconda.org channel stackless.

  1. Add the channel to your configuration:

    $ conda config --add channels stackless
  2. Add the (meta-) package "stackless":

    $ conda install stackless

The package "stackless" utilises the conda feature mechanism to replace the regular C-Python by Stackless-Python.

Unix and Linux users

Please use the source code to compile your own copy of Stackless Python or have a look at Miniconda.

Mac OS X users

These installers replace your existing Python installation. Note that Stackless should work exactly like standard Python, if the Stackless functionality is not used.

Microsoft Windows users

If you do not wish to compile Stackless Python yourself, we provide precompiled MSI installers. These installers can be used instead of the corresponding regular C-Python installer. Alternatively you can install them alongside C-Python, if you choose the "Install just for me" option.

PyPI Installer


This installer is now deprecated, because

  • it is not compatible with newer Linux distributions
  • it depends on a misfeature of the ancient distutils
  • Miniconda provides a better alternative


On Debian based system the pip installer needs to compile some missing modules. Therefore you need to install various development packages. See https://bitbucket.org/akruis/slp-installer/issue/5.

If you are using Python 2.7.x (x>=3) on Linux amd64 or Windows you can use the PyPI stackless-python installer. It works with pip or easyinstall from distribute or setuptools. It is compatible with virtualenv. Simply run:

> pip install stackless-python


> easy_install stackless-python
