First tool to install for checking plugin compatibility

Perfect for Debugging

Thank you for this ingenious plugin. It has already saved me hours of work debugging. It is also extremely helpful when optimising your own plugins. I have never had any problems with Query Monitor. I can only recommend it to every developer to use it as well.

Must have

One of my must haves for plugin development from the beginning.

Tenia un problema de carga en el wordpress y consegui sacar el error en menos de 5 minutos

Great, just one thing...

...it would be nice to have an option to deactivate the plugin on mobile devices. I noticed that it slows down the loading and time to be able to interact with the pages significantly. Sure, sometimes it would be useful to have it on mobile as well, and that could be added as an option.
Otherwise it's a great, no the best plugin for that use case 😀👍

Developer essentials - been around forever. And keeps getting better.

Happy Software

I discovered the "Set authentication cookie" today (which solved a problem I had in a really smart way). Thank you, everything about this plugin makes me happy (UI, Code, Concepts, Update-Frequency, Reliability, ...)

An valuable thingy that provides detailed insights

Its user-friendly interface and compatibility with other plugins and tools make it a great addition to any developer's toolkit. I highly recommend it to anyone looking to improve their WordPress site's performance.
