I use syncthing to manage the synchronization of files between local laptop and remote development server. The software code base is upwards of 20 years and has dependencies on Windows for runtime. I can run unit tests locally on very fast MacBook Pro or run it much slower on Windows VM. With syncthing I can easily edit files locally or remotely and they are available locally for source control.

The worst problem is refining the ignore settings to ensure only code is synced preventing conflicts on derivative files and that some rule doesn’t overlap code file names.

Try unison, it's built for this use case.

I like Unison, though I found Mutagen a bit better.
