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

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

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.

Please use the source code to compile your own copy of Stackless Python.

Note: We need volunteers to build and develop Stackless for macOS.

If you use the marvellous Python distribution Anaconda or Miniconda you can install older versions of 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.
