@spockTheGray third party plugins do provide support for VSCode which is free. Or you can use CLion if you already have a license for that or for the whole IntelliJ suite.
It’s not straightforward to setup but once you manage to do it the first time it’s all there. I’ll see if I can add some auto setup stuff to the CLionSourceCodeAccess plugin to provide all the VsCode and YouCompleteMe files and options needed. That should make it even easier to get it up and running
