Xdebug Cloud is hosted service that allows for Xdebug debugging sessions to be proxied through an online service bypassing networking complications.
With Xdebug Cloud both your IDE and Xdebug make a connection to a hosted service. By having this proxy service, Xdebug no longer needs to connect directly to your IDE. This bypasses complex networking set-ups, related to Vagrant, Docker, NAT networks, and more.
Xdebug Cloud needs support in your IDE. At the moment, only PhpStorm has support for Xdebug Cloud.
