Why Developers Choose NeoVim Over Vim

Vim originated as the successor to the original Unix vi editor, while NeoVim is a fork that aims to improve developers' daily workflow.

1. Project maintenance and feature improvements

Vim’s core development is led by a single maintainer and primarily occurs on mailing lists, resulting in a codebase that is harder to maintain and less community‑friendly. NeoVim, by contrast, focuses on extensibility and usability, adding features such as a built‑in terminal, asynchronous execution, and popup windows, which were later adopted by Vim under community pressure.

2. Code completion (LSP)

The Language Server Protocol (LSP) defines how editors communicate with language servers to provide syntax checking, code completion, type hints, and more. NeoVim ships with out‑of‑the‑box LSP support and is configured via Lua, whereas Vim requires an external plugin to obtain the same functionality.

3. Better plugin ecosystem

Both editors have rich plugin ecosystems, but NeoVim allows plugins to be written in Lua, a more general‑purpose language, making IDE‑like features easier to configure. This reduces the complexity of setting up advanced functionality compared to Vim’s traditional Vimscript‑based plugins.

4. Parallel startup

NeoVim can start plugins in parallel, which speeds up initialization, especially when several plugins have multi‑second load times.

5. Embeddable editor

Because NeoVim’s codebase is more maintainable, it is easier to embed the core editor into other applications, such as integrating a full‑featured editor into VS Code.

6. Configuration file location

Vim stores its user configuration in ~/.vimrc, which is not under the XDG standard. NeoVim follows the XDG specification, placing its main configuration file init.nvim in ~/.config/nvim/, simplifying backup and migration across Linux distributions.

7. Optimizations in NeoVim

NeoVim optimizes command execution. For example, the command :g/<pattern>/d in Vim finds matching lines, copies them to a register, and then deletes them, performing four steps. Adding an underscore ( _) as in :g/<pattern>/d _ skips the copy step, making the operation faster. NeoVim automatically applies this optimization when it detects multi‑line deletions.

8. Better out‑of‑the‑box defaults

NeoVim enables several sensible defaults: autoindent is on, background defaults to dark mode, and hlsearch (highlight all matches) is enabled, providing a more ready‑to‑use experience for new users.

Conclusion

Vim was created to improve the original vi editor, and NeoVim was created to improve Vim. The enhancements in maintainability, built‑in LSP, Lua‑based plugins, parallel startup, XDG‑compliant configuration, and performance optimizations explain why many developers now prefer NeoVim.
