Which Content Management Systems (CMS) do you use?

Recently, these have been the main systems we have been hired to work on:

Drupal 7

Drupal 8

Drupal 9

WordPress

Moodle

Magento

Wix

There are quite a few older sites that we help with that are custom PHP, CSS (incl. Less CSS), Javascript, and so on.

We try to urge smaller clients to stick with WordPress or Wix, as they are the easiest to change, maintain, and update. Many clients do their own updating.
