Duplicate your posts to all the sites in your network without complications.
With Network Post Duplicator, you can publish content once and duplicate it across multiple sites in your WordPress multisite. This helps you save time, avoid repetitive tasks, and keep a consistent publishing workflow.
Simple configuration: From the plugin settings screen, you can select the post types where duplication is enabled and define how you want duplication/synchronization to behave.
Intuitive duplication from the editing screen: Once activated, the plugin adds duplication controls in the post editor so you can choose target sites and duplicate with a few clicks.
Optimize your workflow: Manage network-wide publishing faster and focus on content quality instead of recreating the same post site by site.
Post synchronization: Keep duplicated posts aligned when the parent post is updated.
Free version features: 
1. Duplicate posts across selected sites in your multisite network. 
2. Enable duplication per post type from plugin settings. 
3. Duplicate directly from the post editing screen. 
4. Basic synchronization support for duplicated posts. 
5. Security hardening and multisite-safe blog switching patterns.
PRO version features: 
1. Parent-child relationship map with sync status (<code>npd_children_map</code>). 
2. Selective Sync policy (global and per post override). 
3. Post meta duplication/sync with blacklist and replace/merge mode. 
4. SEO presets for Yoast, RankMath, and AIOSEO. 
5. ACF support for complex field types (image, gallery, file, relationship, post_object). 
6. Advanced media synchronization (featured image mapping, embedded uploads URL rewrite, Gutenberg/gallery ID remap). 
7. Bulk duplication actions with batch processing. 
8. Child-to-parent quick navigation from the metabox. 
9. Dedicated top-level admin menu and modern settings UI. 
10. Custom capability (<code>npd_manage_duplication</code>) and additional nonce/capability hardening.
