SpaceVim vs VimR: What are the differences?
Developers describe SpaceVim as "Like spacemacs, but for vim". SpaceVim is a Modular configuration, a bundle of custom settings and plugins, for Vim. It got inspired by spacemacs. On the other hand, VimR is detailed as "Refined Vim Experience for OS X". Project VimR is an attempt to refine the Vim experience. The goal is to build an editor that uses Vim inside with many of the convenience GUI features similar to those present in modern editors for Mac.
SpaceVim can be classified as a tool in the "Tools for Text Editors" category, while VimR is grouped under "Text Editor".
SpaceVim and VimR are both open source tools. It seems that SpaceVim with 11.5K GitHub stars and 957 forks on GitHub has more adoption than VimR with 4.15K GitHub stars and 121 GitHub forks.
