Neovim is a refactor, and sometimes redactor, in the tradition of Vim (which itself derives from Stevie). It is not a rewrite but a continuation and extension of Vim. Many clones and derivatives exist, some very clever—but none are Vim. Neovim is built for users who want the good parts of Vim, and more.
Neovim is a Vim-based text editor engineered for extensibility and usability, to encourage new applications and contributions.
