Download Pynsource

Download the latest releases from GitHub. 👈



Unzip and drag app into the Applications directory.

Mac users, Pynsource is not codesigned (costs money!) , so please right click open the application the first time you run it.
👉 Big Sur and Monterey users: please run the following command in a terminal: xattr -dr /Applications/ Simply do this once this after unzipping Pynsource and dragging it into /Applications, then you'll be good to go.

Windows 10


Unzip and run the installer.


Install via the ubuntu software center, just search for 'pynsource'. Or install via the Pynsource snapcraft page. Or unzip and run the standalone executables available for Ubuntu 18.04 and 20.04. The benefit of the linux binaries is that they can be registered with a Pro license (snaps cannot).


Special rare builds running the older version 1.77 (not recommeded):

Ubuntu Snap Installation

Visit Linux snap installer (one-click install on any Ubuntu distro) or simply

sudo snap install pynsource

Upgrades should happen automatically, but if you want to force it
sudo snap refresh

Note re snaps under Ubuntu 16.04 Due to a bug in Snapcraft, if you are trying to install the snap on Ubuntu 16.04 the GUI installer will not work and you will have to install from the terminal.

sudo snap install pynsource
sudo snap install core
Note: The snap Pynsource cannot be registered with a Pro Edition license - please download a Pynsource standalone linux executable above, if you want to use a Pro Edition license.

Pro Edition

An affordable, commercial Pro Edition is also available with extra features like zoom and the ability to drag to connect shapes.

Simply download the regular builds and then purchase an rego key from here.
