Secure Custom Fields is a free plugin that can be downloaded from the WordPress plugin directory. SCF allows you to create Custom Post Types, custom taxonomies, and custom fields. You can assign custom fields to post types which show on on the admin edit screen where you can enter their values. SCF has more than 70,000 active installs. It has more than 30 field types and comes with easy to use PHP functions for displaying fields in theme templates. It includes the Repeater, Flexible Content, Gallery, and Clone fields. You can also create Admin option pages and use PHP to create Gutenberg blocks.
Secure Custom Fields is a fork of ACF Pro made in late 2024. While feature parity may have drifted, SCF can be used with most third party themes and plugins that support ACF. This has made SCF popular for people who want to avoid a subscription.
