All downloadable binaries and checksums are mirrored here. If you wish an independent source to verify checksums from, it may also serve that purpose.

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:


Unix and Linux users


The following GNU/Debian 7.2 64-bit packages (/opt is installation root) are provided by a third party and are mirrored (from

Other variants

Please use the Mercurial repository to compile your own copy of Stackless Python. The directory structure follows that of the main Python repository.

Alternatively, for the versions of Stackless which it supports, you may be able to make use of the PyPI stackless-python installer. See below for details.

Alternatively, for the versions of Stackless which it supports, you may be able to make use of the StaticPython project. StaticPython is a custom distribution of both Python and Stackless Python statically linked for 32-bit Linux, so it makes it possible to try the supported versions of either without actually installing them.

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 three ways in which you can install a precompiled version. The most straightforward way is using one of the provided installers, while the less straightforward way is converting an existing Python installation into a Stackless one.


Stackless Python is a replacement for Python, as such it installs as the version of Python it is an enhanced form of. You will need to uninstall your normal Python installation before you can install the same version of Stackless Python.

PyPI Installer


On Debian based system the pip installer needs to compile some missing modules. Therefore you need to install various development packages. See

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

Binary Snapshots

If you are downloading one of these binary snapshots, you are intending to create a Stackless Python installation through modifying a standard Python installation. You may do so in this way:

  1. Download a standard Python installer.

  2. Run the standard Python installer.

  3. Download the binary snapshots from those which are listed below, which has the same version as the standard Python installer you downloaded:

  4. Extract the binary snapshot archive into the installed Python directory.
