Welcome to Cartoque!
Cartoque is a free, web-based CMDB tool built to replace an existing application we used to have at work. It's built on top of the Ruby on Rails web framework.
The app may not be totally ready for your use case now, but I'd really love to hear your thoughts or feedback ! The goal of this project is to make the original application evolve in a product generic-enough for use in any small to medium datacenter. Actually today the application comes with opinionated choices that might not fit your needs (see Requirements) but I'm ready to discuss them with you.
In the next few months I'll be 100% focused on improving documentation, making it easier to install, and making it better for everybody who'd like to use it.
