Sync Advanced Custom Fields
with 100% field key & repeater integrity.
Advanced Custom Fields powers the modern WordPress editorial experience, but its nested repeaters, clone fields, and hidden `_field_key` references are notorious for breaking during manual migrations. EZ Page Sync ensures every ACF field, sub-field, and relationship moves seamlessly from staging to live.
Key Specifications
The Problem
The Hidden Complexity of Syncing ACF Metadata
ACF doesn't just store values in `wp_postmeta` — it relies on a strict internal map of field keys, serialized arrays, and relational IDs.
Broken Field Key Reference Mapping
ACF stores a companion `_field_name` meta row pointing to `field_xxxxxxxx`. Omitting or mismatching these keys causes ACF to render empty fields on live.
Corrupted Repeaters and Flexible Content
Nested repeater rows and flexible layout blocks contain complex serialized multi-dimensional arrays that corrupt easily under search-replace.
Relational Post & Taxonomy ID Disconnects
Post Object and Relationship fields reference staging post IDs that don't match production IDs, linking pages to the wrong content.
The Solution
Intelligent ACF & Custom Meta Serialization Engine
Built by developers for custom WordPress architectures, EZ Page Sync handles deeply nested ACF data structures with zero manual cleanup.
Full ACF Pro & Core Meta Support
Synchronizes all ACF field types: Text, Wysiwyg, Image/File, Repeater, Flexible Content, Clone, Group, and Relationship fields.
Deep Field Key Preservation
Preserves the exact relationship between post meta values and their underlying ACF field definitions (`field_xxxxxxxx`).
Smart No-Op Detection
Identifies unchanged custom field keys and skips unnecessary database writes, maintaining clean `wp_postmeta` tables and avoiding bloat.
Yoast SEO & Astra Meta Support
Also syncs third-party metadata from Yoast SEO, Rank Math, Astra theme settings, and custom developer meta boxes.

Your live template reads the exact meta values and renders custom layouts identically to staging.
Frequently Asked Questions
Questions about Developer Tooling
Does this work with ACF JSON local files?
Yes! Whether your field groups are saved in the database or via local `acf-json` files in your theme, EZ Page Sync correctly associates field keys and syncs all page-level meta values.
Will image IDs inside ACF Image or Gallery fields sync?
Yes. EZ Page Sync recognizes media references inside ACF fields, transfers the files to production if they don't exist yet, and saves the new attachment ID in the custom field.
Can I sync custom postmeta created by my own custom plugin?
Absolutely. EZ Page Sync synchronizes all custom postmeta keys registered to the post, not just ACF fields.

Sync WordPress Staging to Production Without Overwriting Database
Traditional WordPress staging tools force a blunt full-database replacement that wipes live comments, new customer accounts, and form entries. EZ Page Sync selectively pushes only the exact pages, custom post types, and metadata you choose — leaving the rest of your live database completely untouched.
E-Commerce SafetySafely Sync WordPress Pages on WooCommerce Sites Without Losing Orders
Running a database migration on a live WooCommerce store is terrifying: a single overwrite can destroy recent sales, order statuses, inventory counts, and customer registrations. EZ Page Sync enables you to build sales funnels and redesign product landing pages on staging, then deploy them to live production without touching your store's transaction history.
Page Builder IntegrationSync Elementor Pages & Templates from Staging to Live WordPress
Elementor stores complex layout trees and image IDs inside serialized JSON strings (`_elementor_data`). Copying them manually or using basic migration tools breaks layout IDs, corrupts background images, and leaves CSS caches stale. EZ Page Sync parses Elementor data natively, sideloads missing media, and regenerates production styles automatically.
