WordPress is currently the fastest growing CMS software. Initially, WordPress was largely associated with blogs as its main functionality was to allow easy blog experience. Yet, over time, its developers expanded its functionality to allow the creation of more complicated websites and grew it into a content management system rather than a blogging tool. We compiled a short list with the top 10 tools for WordPress developers to help you get the best of it:


Usersnap is a screenshot and bug tracking tool for WordPress developers. Screenshots and bug reports as well as other post and browser information get sent directly to the admin’s dashboard. This plugin lets you annotate and record feedback based on your site visitor’s comments or reviews. It also can help to communicate about issues and/or share feedback between developers, visitors, customers, etc. Once the Usersnap widget is added to a site, a little feedback form or popup is made available for all who peruse the site to leave their feedback.



Roots.io is a set of tools that helps you build better WordPress sites faster by using open-source tools for WordPress application development. Roots.io consists of Trellis, Bedrock, and Sage – three different applications that can be used together or separately to improve your development workflow.

WordPress Codex

The WordPress Codex is essentially an encyclopedia (or, Wikipedia) for WordPress developers. It proclaims itself “…the online manual for WordPress and a living repository for WordPress information and documentation.” It’s an invaluable tool that is easily accessible and ever-growing. Many WordPress users fail to utilize this tool, its guides, and references, and so it has been relegated to this list of lesser-knows.


User switching

User switching can be described as developer best time saver. Ever wondered how to quickly login and logout from your WordPress site in order to view how other viewers see your website? You don’t have to keep logging in and out of your site, you can now use this plugin to switch between different users, saving you a great deal of time. This plugin allows you to switch between registered users without having to login in and out. When you install and activate, you will see new menu on the WordPress admin bar called Switch off. With a click on a button you can easily and quickly switch WordPress users.

Debug Bar

Debug Bar adds a new menu called Debug at the admin bar. Click on the menu, and it will neatly display information like cache, total queries, total queried time, and memory usage that will be very useful in the debugging process. In addition, you may also see some PHP Warnings and Notices that occur when you enable WP_DEBUG.

WP Developer Assistant

WP Developer Assistant is “essentially is a toolkit that makes life as a WordPress developer easier.” Does cool stuff like customizable PHP errors, global variable dump, table modification, execute queries, phpinfo(), and much more.

Theme Unit Test

This Theme Unit test installs a long list of circumstances for testing with images of different sizes, post types, etc. This testing would take hours or days normally, therefore Theme Unit Test tool is hugely convenient and time-saving.

Regenerate Thumbnails

If you change the default images sizes in your site’s media settings, only images that you upload from that point on will be sized to your new dimensions. Older images though will still have the old image sizes. This can cause image distortion.

Regenerate Thumbnails scans through all of your site’s images and regenerates the images to the newly defined dimensions.

Query monitor

Query Monitor lets you view all the ongoing database queries, as well as the rows being affected. You can also view rewrite rules, hooks fired on the current request, PHP errors and warning and even template filenames and parts. Furthermore, Query Monitor is one of the very few WordPress plugins for developers that let you keep track of AJAX calls, REST API requests and redirects. So if you are working with the WP REST API plugin, Query Monitor can prove to be very useful.
