What is OneMeta?
OneMeta is a free, open-source WordPress plugin for creating and managing custom meta fields. It gives you a visual drag-and-drop builder, 14 field types, repeater fields, conditional logic, live PHP code preview, and a full REST API — all in a single plugin that weighs just 239KB.
It is designed as a modern, lightweight alternative to plugins like ACF (Advanced Custom Fields), with no premium tiers, no license keys, and no external dependencies.
What Can It Do?
Visual Field Builder Build field groups using a drag-and-drop interface directly in your WordPress admin. Add fields, configure labels, keys, descriptions, placeholders, and advanced options — all without writing any code.
14 Field Types OneMeta ships with 14 carefully chosen field types covering every common use case — from simple text inputs to media uploads, choice fields, and repeatable row groups.
Post Meta and User Meta Assign field groups to any public WordPress post type — posts, pages, or custom post types — or switch to User Meta mode to add custom fields to WordPress user profile pages.
Live PHP Code Preview As you build your field group, a live preview panel shows the exact PHP code that will be generated. You can copy or download this code at any time.
Export as PHP Export any field group as a clean PHP file and use it in your theme or plugin without OneMeta installed. This is particularly useful for ThemeForest themes and client projects.
Repeater Fields Create repeatable row groups — team members, portfolio items, FAQs — with any combination of sub-fields per row.
Conditional Logic Show or hide fields dynamically based on the value of another field using four operators: ==, !=, contains, and !contains.
REST API A full REST API under the onemeta/v1 namespace provides CRUD endpoints for all field group operations.
