Fury is a very opinionated configuration management tool, operating in a similar space to Puppet, Chef, Ansible, Saltstack and the like. It's not at all production-ready, you should never use it.
I wrote it because I have strange opinions about what my ideal config management system would be, and why I think all existing systems are getting it fundamentally wrong. It's very unlikely that I'm correct, but exploring the depths of my wrongness is entertaining, and might result in something that I at least like using.
This is not an official Google project, if you hadn't guessed by now.
