Sidebar Diff brings revision comparisons directly into the editor so you don’t have to leave your flow.
<ul>
<li>Always-visible panel in the editor sidebar</li>
<li>Live comparison of your current edits vs. last saved copy</li>
<li>Optionally compare against any revision from the dropdown</li>
<li>Per-block grouping with per-paragraph highlights (insertions and deletions)</li>
<li>Zero front‑end impact; editor-only assets</li>
<li>Improved diff highlighting with color-coded line indicators</li>
<li>Dark mode support for WordPress 6.8+ compatibility</li>
<li>Responsive design optimized for different screen sizes</li>
<li>Keyboard shortcuts (Ctrl+D/Cmd+D) to toggle diff panel quickly</li>
<li>Performance optimizations with lazy loading and debounced calculations</li>
</ul>
Why this isn’t a duplicate: Existing revision/workflow plugins (e.g., PublishPress Revisions) provide queues and separate compare screens. Sidebar Diff embeds an always-visible diff inspector inside the editor sidebar for continuous awareness.
<h3>Privacy</h3>
The plugin does not transmit data to third parties, set cookies, or track users. Editor-only scripts run for logged-in users with edit capabilities.

These tools are intended to be used by WordPress developers for testing and debugging.
The backup tool lets you do a quick backup of individual MySQL tables by duplication into the same database, i.e. using “CREATE TABLE copy LIKE orig; INSERT INTO copy SELECT * FROM orig;”. 
Useful for testing when you know only some tables will be changed so you don’t have to save and restore the entire database. 
Most useful for repeated testing, i.e. backup table(s), test, restore table(s), test, restore table(s), … test, restore table(s), delete backup.
The diff tool shows the rows in the selected tables that were inserted, updated or deleted. 
For updated rows the columns that have changed values have the values highlighted – red for the original value and green for the new value. 
Although large values are truncated in table cells the full value is available by clicking on the table cell. 
Further, serialized values are prettified using JSON.stringify( value, 4 ). 
The diff tool is intended for viewing the effect on the database tables of a small number of WordPress operations, 
i.e. it is not suitable for testing a large number of WordPress operations.

This plugin requires at least PHP 5.4.

Database Debugging Tools for Developers

This is exactly what I needed, some way to monitor database changes to see what is happening under the hood ... this plugin did exactly that, and provided an easy way to keep my database safe, and still have a full diff view of database changes!
