ACF Post-2-Post

78 Quality Score

Active Installs

16/30

At roughly 3,000 active installs, it is a niche utility that has not crossed into mainstream awareness, but the installs-to-score ratio reflects strong engagement within its small audience.

Update Freshness

25/25

The plugin was last updated on July 9, 2025, and is confirmed compatible with WordPress 6.9.4, indicating an actively maintained codebase, though the lack of a stated minimum PHP requirement leaves some uncertainty about server-side support.

User Rating

15/15

With a perfect 100/100 from 39 ratings, every user who reviewed it gave it top marks, which is impressive but based on a modest sample size that may not reflect broader conditions.

Support Health

8/15

Support health sits at a middling 50 because there are zero public support threads, meaning users have not needed help, or more likely, that support is handled privately and visibility is limited.

WP Compatibility

15/15

Full marks for compatibility come from confirmed WordPress 6.9.4 testing, a low minimum WP requirement of 4.0, and clean operation with ACF as its sole dependency.

What It Does

ACF Post-2-Post automatically mirrors bidirectional relationships between WordPress posts and custom post types, so when you connect Post A to Post B in an Advanced Custom Fields relationship field, the inverse link is created on Post B without manual effort. It works as a lightweight add-on for ACF, removing the tedious task of editing both sides of a connection. The plugin handles synchronization in the background as you save or update content.

Who It's For

This plugin is best for site builders and developers who already rely on Advanced Custom Fields to model content relationships, particularly those running real estate listings, client-matter tracking, author-article networks, or any workflow where two post types must stay in sync. It suits small-to-mid-traffic sites with a clear relational content model rather than large editorial operations. It's especially helpful for teams that have hit the pain point of manually updating connection fields on both ends of a relationship.

Who Should Skip It

If you do not use Advanced Custom Fields, or if your relational content needs are satisfied by a single-direction relationship field, you have no reason to install this plugin. Sites that need full-featured post-to-post mapping with custom queries, connection metadata, or REST API endpoints should look at Posts 2 Posts or MB Relations instead.

The Bottom Line

ACF Post-2-Post earns a 69.41/100 quality score and does one specific job reasonably well, supported by a perfect user rating from 39 reviewers and active maintenance into mid-2025. The small install base and absence of a public support track record mean you should test it on staging before relying on it in production. For ACF users tired of manual relationship mirroring, it's a worthwhile utility; for everyone else, skip it.
