# CPT UI Pro > The complete WordPress content modeling toolkit — register custom post types and taxonomies (free, forever), then extend with display blocks, admin management, multisite support, and developer hooks (Pro, $99 one-time). By [WebDevStudios](https://webdevstudios.com) — a WordPress development agency. ## What is CPT UI? CPT UI is a WordPress plugin that provides a UI for registering custom post types (CPTs) and taxonomies — the structural content layer that ACF, page builders, themes, and other plugins build on top of. It has been actively maintained since 2011 and is installed on over 1,000,000 active WordPress sites with 20M+ all-time downloads. CPT UI does not replace field plugins (ACF, Meta Box), themes, or page builders. It is the foundation those tools rely on. ## Products ### CPT UI — Free - Available at: https://wordpress.org/plugins/custom-post-type-ui/ - Price: $0, unlimited sites, forever - Core features: register unlimited custom post types, register unlimited custom taxonomies, import/export configuration, Get Code (PHP export), full REST API support, WordPress.org community support - License: GPL v2 ### CPT UI Pro - Available at: https://pluginize.com - Price: $99 one-time (launch pricing, limited time; regular price $149) - License: 1 site, GPL v2 - Includes: 6 months of updates and priority email support - Guarantee: 30-day money-back, no questions - Includes everything in Free, plus: **Front-end Display** - Query Loop block (grid and list layouts for any CPT, pagination, custom field display) - Taxonomy filter blocks (live-filtering dropdowns and tag clouds, no JavaScript required) - Single-post block templates (per-CPT layout control without custom PHP) - Shortcode builder **Admin UI Customization** - Column Builder (drag-and-drop custom columns in post list tables) - Advanced Filters (taxonomy, meta, date, author, and status filter dropdowns) - Screen Options Panel (per-user column visibility controls) **Multisite / Network** - Network-level CPT registration (register once, propagate to all subsites) - Per-site inheritance control - Push config to subsites from network dashboard **Developer Tools** - `cptui_pro_post_types` filter — merge, modify, or replace registered post types programmatically - Auto-discovery hooks — themes and plugins can register CPTs via CPT UI Pro without user interaction - Programmatic registration API — drive registration from JSON config, environment variables, or CI pipeline - Full REST API support with Pro-specific endpoints ## Compatibility Works alongside ACF, Meta Box, Elementor, Beaver Builder, Divi, Bricks, and all major WordPress themes and page builders.

ACF, Meta Box, and other field plugins work on top of that structure. They are complementary, not competing. **Is CPT UI Pro a subscription?** No. One-time purchase. Plugin works forever. Renewal at 30% discount is optional for continued updates after 6 months. **Is the free plugin still maintained?** Yes. Free has been actively maintained since 2011 and will be forever. **What is the license?** GPL v2. Both free and Pro.
