Simple and extensible

It is a great help when investigating problematic cases in support of our review plugins

We are using it in our plugin support

I couldn't do without it

Helpful tool


A plugin without which I cannot imagine my work. It would definitely be much more difficult.


it must be!


Debug Bar is still listed in WordPress’s own developer documentation as a go-to debugging tool, yet it hasn’t been updated in over a year and throws PHP errors. It’s a clear example of Automattic promoting a tool while failing to maintain it - a pattern that’s become too common. For a plugin they recommend, its neglect is frustrating and undermines developer trust.


Seemingly abandoned

Adds a debug menu to the admin bar that shows query, cache, and other helpful debugging information.

<li>Add new cron events.</li>
<li>Bulk delete cron events.</li>
<li>Add and remove custom cron schedules.</li>
<li>Export and download cron event lists as a CSV file.</li>

WP Crontrol

I use this plugin all the time when testing cron events or problem solving. As far as I am concerned it is an essential part of a developer's tool kit.

Must have plugin for developers

As everybody else say: This plugin was great, but after releasing an automatic update with a fatal error, about 200 000 sites world-wide went down - among others some of our customers'.

We have no reason to think that this was intentional, but nonetheless it's unacceptable, and there's nothing that says this developer won't do this again.

Do not install.

From great to disaster

Useful tool


WP Crontrol helped me spot a mistake that I made in my wp_schedule call.
