Craft Delta

Inline revision diffing for Craft CMS 5. Compare any two revisions, drafts, or the current version of an entry and see exactly what changed — word-level for text, block-level for Matrix, and value-level for everything else.

Requirements

• Craft CMS 5.8+
• PHP 8.2+

Installation

composer require zeixcom/craft-delta
php craft plugin/install craft-delta

Features

• Word-level text diffing for Plain Text and CKEditor fields
• Matrix diffing — added, removed, modified, and reordered blocks
• Relational field diffing — Entries, Assets, Categories, Tags, Users
• Table field diffing — row and cell-level changes
• Option field diffing — Dropdowns, Radios, Checkboxes, Multi-select
• Scalar diffing — Numbers, Dates, Lightswitches, Colors, Money, etc.
• Draft comparison — compare drafts against revisions or the current version
• Multisite support — diffs are site-aware
• "Changed only" filter — toggle unchanged fields on/off
• Diff summary stats — fields changed, additions/deletions
• Translations — English, German, French, Spanish, Italian, Dutch, Portuguese, Polish

Usage

Open any entry with at least one revision. A "Compare Revisions" button appears in the sidebar. Click it to open the diff slideout.

Use the two dropdowns to select which versions to compare — Current, any draft, or any revision. The diff loads automatically when you change the selection.

• Click the swap button to reverse the comparison direction
• Toggle "Changed only" to hide unchanged fields

Settings

Configure under Settings > Plugins > Craft Delta:

Setting	Default	Description
Diff Context Lines	3	Unchanged lines shown around changes
Max Field Length	50,000	Characters before showing a simplified diff
Show Unchanged Fields	Off	Show unchanged fields by default

Extending

Register custom differs for third-party field types:

use zeixcom\craftdelta\services\FieldDiffService;
use zeixcom\craftdelta\events\RegisterDiffersEvent;

Event::on(
    FieldDiffService::class,
    FieldDiffService::EVENT_REGISTER_DIFFERS,
    function (RegisterDiffersEvent $event) {
        $event->differs[\myvendor\fields\MyField::class] = MyFieldDiffer::class;
    }
);

Custom differs must implement zeixcom\craftdelta\differ\DifferInterface.

Roadmap

Extend the plugin with the most popular third-party field types like NEO, Hyper, etc.
