Pollux

Pollux is a plugin for site builders and developers who need to register custom post types, taxonomies, meta boxes, and global settings without writing PHP code. Instead of a visual builder, it uses YAML markup on its settings page to define configurations, which can be faster and more precise for those comfortable with structured data.

• YAML-based configuration: Define all custom structures using simple, readable YAML markup directly in the plugin settings. No need to edit theme files or write PHP.
• Custom post types and taxonomies: Register any number of post types and taxonomies with labels, supports, and visibility options. Works with any theme.
• Meta boxes and fields: Add custom meta boxes to posts, pages, or custom post types. Supports various field types and conditional logic for dependencies.
• Global settings and archive page meta: Create site-wide settings pages and customize archive page metadata without additional code.
• Meta Box plugin integration: Pollux relies on the Meta Box plugin for rendering meta boxes. If not installed, it prompts you to install it, keeping the core lightweight.
