Plugins for the WordPress developer

Not all plugins are specifically for developers, but in general I use all these plugins when developing and creating websites. Many of the plugins on this list make things easier, show data, or allow debugging.

Query Monitor

The main plugin for debugging. Shows everything and more (Database Queries, PHP Errors, Hooks and Actions, Queued Scripts and Styles, Theme Template Files, Languages ​​and Translations, Rewrite Rules, Block Block Editor, HTTP API Calls). Even allows logging via do_action( ‘qm/info’, $var);

Query Monitor Extend

Addon for the Query Monitor plugin. Shows additional data:

• ACF support
• included files
• constants
• thumbnail sizes

Debug This

Similar to Query Monitor. But you can also use them together. Moreover, sometimes it even needs to be used together with Query Monitor, since there is a lot of information that is not available in Query Monitor.

Entity Viewer

Sometimes an indispensable plugin. Shows properties and custom fields for any entity: posts, taxonomies, users, comments.

WP Crontrol

WP-Cron tracking plugin. Allows:

• View all cron events along with their arguments, recurrence, callback functions, and their next execution time.
• Edit, delete and immediately run any cron events.
• Add new cron events.
• Bulk deletion of cron events.
• Adding and removing custom cron schedules.
• Export cron events as a CSV file.

Transients Manager

This is a developer tool that provides a user interface for controlling transients.

You can view, search, edit and delete transients. A toggle on the toolbar allows you to pause temporary updates for easier testing and debugging.

User Switching

Plugin for switching users. Instantly logout and login as the desired user. This is useful for testing environments, assisting clients on WooCommerce sites, or for any site where admins need to switch between multiple accounts.

An indispensable solution when developing various personal accounts and other user-related functionality.

User Role Editor

A well-known plugin for editing user roles and capabilities. You can create new roles or edit existing ones. In general, sometimes it’s convenient.

KAGG Generator

When developing WordPress, sometimes you need to create large databases with hundreds of thousands of records. Existing plugins can generate test content, but very slowly, with a typical rate of 1000 messages per hour.

KAGG Generator plugin is capable of generating millions of records in minutes.

Safe SVG

I installed the plugin from the series, activated it and forgot about it. Includes support for SVG images, and when loading such images, it cleans them for safe use.

WP Rollback

The plugin allows you to rollback any theme or plugin from WordPress.org to any previous (or newer) version without any manual hassle.

Works the same as the plugin updater, except you roll back (or downgrade) to a specific version.
