Papi

Papi is a developer-focused tool for managing custom fields and page types in WordPress sites. It replaces the typical admin UI with a code-driven approach, giving you full control over field definitions and database storage. Only field values are saved—no metadata about field types—making it easy to start fresh or migrate databases.

Key features:

• Code-based field definitions: Create and manage all fields through PHP code, not a visual interface. This ensures version control, repeatability, and no accidental changes via the admin panel.
• Page type selection on creation: When adding a new page or post, you choose from predefined page types tied to that post type. This enforces structure and consistency across content.
• WordPress-native UI: All fields are rendered using standard WordPress styling and interactions, so editors and authors work in a familiar environment.
• Minimal database footprint: Only the actual field values are stored in the database. No extra references to field types or configurations are saved, keeping your database lean and portable.
• Open source and free: The project is available on GitHub under an open source license. Contributions and stars help others discover and improve the tool.
