Carbon Fields is a developer-oriented PHP library for creating custom fields in the WordPress admin panel, installable via Composer. It supports fields for posts, taxonomy terms, users, comments, options pages, navigation menus, widgets, and Gutenberg blocks using a declarative, expressive API.

Use cases

  • add custom fields to WordPress post types
  • create theme options pages in WordPress
  • build Gutenberg blocks without writing JavaScript
  • create repeatable nested field groups in WordPress admin
  • add custom fields to taxonomy terms, users, and comments
  • build custom WordPress widgets with fields
  • add fields to WordPress navigation menu items

When to choose

  • you are a PHP/WordPress developer who prefers defining fields in code rather than a GUI
  • you need custom fields across many WordPress content types including widgets and nav menus
  • you want a free, fully-featured alternative to freemium custom field plugins
  • you want to create Gutenberg blocks declaratively in PHP

When to avoid

  • you need a point-and-click admin interface for building fields without coding
  • your project is not WordPress-based
  • you are not comfortable working with PHP and Composer
