We use Mutagen for Garden's hot reloading mechanism. (Garden is a dev tool for K8s and hot reloading enables users to sync changes directly to a prod like dev environment as opposed to doing a rebuild and re-deploy).

It really is a fantastic piece of technology and completely transformed the whole experience (we were using good 'ol rsync before). In particular it works seamlessly across platforms.

If anyone's interested in how we use it, it's here: https://github.com/garden-io/garden/blob/master/core/src/plu...
