Become a sponsor to Derick Rethans

Hi there!

I am Derick, and I am the creator and sole maintainer of Xdebug, PHP's debugger.

The main areas of Open Source that I work on are:

Please help me to continue to work on these projects, by sponsoring me here on GitHub.


155 sponsors have funded derickr’s work.


If I reach a $2500/month, I will be able to spend enough time to maintain Xdebug. That's what you want too, right? I'll also start sending my monthly updates to you as well, way before they show up on my web site.
