A Node virtual machine

Ideal Node.js hosting service
Here’s the URL of a GIT repo, containing a Node app. Run it with forever.
I want to be able to do a tail -f on the log so I can see what’s going on. 
And to view its file system, perhaps through a browser-based JS app.
I think that’s about it. I give you a URL, you run it.I know some services get close, but I don’t want close. I want just this. A Node virtual machine.
