Holochrome by Ryan

Holochrome allows you to easily log in and switch between your AWS accounts using a single key stroke. It is built on top of the instance metadata service and therefore encourages best security practices by completely removing the need for static, long-lived credentials. If you want to use Holochrome inside of AWS, simply spin up an AWS instance with an IAM role and Chrome installed. If you want to use Holochrome on your local dev machine, check out AdRoll's Hologram (https://github.com/AdRoll/hologram) which will run the instance metadata service for you.
