Custom Post Type UI

Custom Post Type UI, or CPT-UI for short, is a free plugin for defining Custom Post Types and custom taxonomies. The plugin has more than 900,000 active installs and works well with Advanced Custom Fields. The plugin is available from the WordPress plugin directory and there is documentation available.

CPT-UI makes available all of the setting options you might need. Although the long page of options may seem overwhelming, the long list of labels can be left at their defaults and ignored.

Custom Post Type UI - The Good

CPT-UI is very popular and easy to use.
It is kept up to date by the developer and documentation is good.
There is an option to export your CPT or taxonomy to import on another site.
There is an interface that shows the PHP code in case you want to create a plugin and stop using CPT-UI.

Custom Post Type UI - The Bad

You need to be careful about changing the name of your Custom Post Type to avoid accidental duplication.
