Plone is a open source CMS written in Python with a focus on functionality, customizability and security out of the box.

This list is intended to fill that gap, and create a shared knowledge about common products and techniques.

This list only covers add-ons that work with the latest major versions of Plone (currently 5.2 and 6) and only those that support Python 3.

Plone 6 comes with a new default frontend called Volto, which is written in React and uses plone.restapi to communicate with Plone. Volto is very extendable in itself. Checkout the awesome-volto list for add-ons to Volto.

Once you have a shortlist, test these add-ons. Here are the main issues you need to test before you install an add-on on a production site:

  • Test all required features. Read but do not trust the documentation
  • Check if the add-on runs on your required version
  • Check if it is maintained
  • Does it have i18n-support, i.e. is the user-interface translated to your language?
  • Does it uninstall cleanly?
  • Check for unwanted dependencies

Once you found an add-on you like, you can ask the community if you made a good choice or if you missed something:

If you can't find something that fits your requirements 100% you can:

  • Adapt your requirements to what is available.
  • Invest the time & money to customize an existing add-ons to better fit your needs.
