CMB2 is a PHP developer's toolkit for building metaboxes, custom fields, and forms in WordPress. It manages meta for posts, terms, users, and comments, and supports creating custom option pages.
Use cases
- add custom fields to WordPress post edit screens
- build metaboxes for posts, terms, users, or comments
- create custom WordPress option/settings pages
- define repeatable field groups in WordPress admin
- build forms for WordPress front-end or admin
When to choose
- you develop WordPress themes or plugins needing custom meta fields
- you want a mature, widely used metabox framework with many field types
- you need option pages or repeatable fields without writing raw admin UI code
When to avoid
- you are not working with WordPress
- you prefer Gutenberg block-based field UIs over classic metaboxes
- you need a framework for non-PHP stacks
