We provide a free access level for anyone interested in using Canopy. We call that access level, or subscription, Canopy Express.
Canopy Express allows users to download the Canopy application's standard installer, which includes approximately 100+ packages pre-bundled into the installer. It also grants access to all 450+ downloadable packages shown in Canopy's Package Manager in Enthought's "free" package repository. While using Canopy Express doesn't require a paid subscription, signing up for a free Enthought account, and logging in to Canopy, will allow you to file reports more quickly and consistently.
The important thing to remember is that if you were previously using Canopy with an Express license and then purchase a subscription, you do not need to re-download the Canopy installer. The new features of your subscription (Canopy's debugger and variable browser, and the Data Import Tool, and more support) will be unlocked once you restart Canopy and log in with your usual account credentials. One of the key benefits of keeping your existing installation is that you will still have your previous Python environment, and all its installed packages, without needing to reinstall everything.
In summary, the underlying Canopy application is the same whether you downloaded it as an Express user or a paid user, and you can unlock new features by upgrading to a paid subscription via our online store.
