Rex vs Cleaver: What are the differences?

Rex: the friendly automation framework. Rex is an automation framework that combines Perl and Secure Shell (SSH) for a portable and highly flexible approach to data center infrastructure management and software deployment; Cleaver: Simply provision, deploy, and manage servers, websites, and apps. A server management tool for hobbyists, startups, web design shops, and managed hosting providers. Minimize server management and app deployment fuss.

Rex and Cleaver can be primarily classified as "Server Configuration and Automation" tools.

Some of the features offered by Rex are:

• Puts you in charge: Rex acknowledges that there is more than one way to manage it. It trusts you to be in the best position to decide what to automate and how, allowing you to build the automation tool your situation requires.
• Easy to get on board: automate what you are doing today, and add more tomorrow. Rex is instantly usable, making it ideal and friendly for incremental automation.
• It's just Perl: Perl is a battle-tested, mature language. Whenever you reach the limitations of the built-in Rex features, a powerful programming language and module ecosystem is directly available at your fingertips to seamlessly extend it even in other languages. So after all, it's not just Perl.

On the other hand, Cleaver provides the following key features:

• VPS
• Hosting
• Deployments
