Fern is a general-purpose asynchronous tree viewer and file explorer plugin written in pure Vim script, supporting both Vim and Neovim without external dependencies. It can be used as a split-window filer (netrw style) or a project drawer (NERDTree style), with an ecosystem of plugins for icons and git status.

Use cases

  • browse and manage files in a vim file explorer
  • replace netrw with an async tree viewer
  • use a NERDTree-style project drawer in neovim
  • open a file tree sidebar in vim
  • navigate project directories from the editor
  • view git status in a vim file tree

When to choose

  • you use Vim 8.2+ or Neovim and want a fast, dependency-free file tree
  • you want both drawer and split-window filer modes
  • you want an extensible plugin ecosystem (nerdfont, git status renderers)

When to avoid

  • you use an editor other than Vim/Neovim
  • you prefer a built-in or GUI file manager outside the editor
  • you need a VS Code-style explorer with rich UI beyond terminal trees
