Otto automatically builds a development environment tailored specifically for your application, with zero or minimal configuration. Otto isolates all your applications into their own local virtualized development environments. It detects the type of application you're developing and configures that development environment for you. For example, if you're developing a PHP application, Otto will automatically install PHP and other related tools for you. Otto supports application dependencies as a first class feature. This makes developing microservices a breeze. Otto automatically downloads, installs, configures, and starts dependencies in your development environments for you.
