Neovim

  • No official first-party GUI is shipped; Neovim itself is a terminal-based editor and only maintains a curated list of third-party GUI front-ends
  • Licensing is not uniform: code contributed after commit b17d96 is Apache 2.0, but code carried over from Vim (tagged vim-patch) remains under Vim's own license

  • No official iOS, Android, or web build
