https://github.com/mobxjs/mobx/ is now monorepo with all the packages, so nothing is deprecated .

In Mobx, a lot of built-in abstraction is there, which leads to less code. In Redux, there is less abstraction and a need to write more code . Mobx is mainly used to develop the application fast and in less time. Redux developed applications generally take time because of their complexity.
