That's exactly the point of remote syncing: whatever changes to code you make locally are nearly instantly available on a remote machine, so you can compile and run your software on a production-like machine. By "supports all tools" I mean that you can run whatever you like on your source code locally, whether it runs through emacs or not, and the result is available remotely. And with bidirectional syncing the reverse is true too.
