I wanted to share a little tool call rtox which is mainly a wrapper for tox which delegates all executions to another remote machine.

I use it daily because my main machine is a laptop and I always find much faster to run tox on a remote machine that has better CPU/RAM/SSD.

https://github.com/pycontribs/rtox -- main page should be more than enough.

Shortly, when you want to run remote you just add [r] before tox. 

I hope you will find it useful.

Cheers
