Otto replaces Vagrant <i>for the common use case</i>: if you&#x27;re just a person who wants to run a personal dev server, they&#x27;d like you to move onto Otto.<p>However, Otto is just a layer on top of Vagrant that automates a lot of the decisions that a dev would usually make. Vagrant is still relevant for other use cases, so they&#x27;ll continue to develop it as a standalone product, too.
