Neovim

What is it?

Neovim is a fork of Vim that keeps everything people love about modal editing while reworking the internals for modern use. It ships with a built-in language server protocol (LSP) client, treesitter-based syntax highlighting, and a Lua API, so plugins and configuration feel like a real programming environment rather than a pile of workarounds.

Why use it?

If you spend your day inside a terminal and want an editor that keeps up with you, Neovim is hard to beat. It starts instantly, works over SSH, and can be shaped into a full IDE without leaving the keyboard. The project is also remarkably active: releases are frequent, the plugin ecosystem is thriving, and moving from Vim is mostly painless.

Key features

• Built-in LSP client for completion, diagnostics, and refactoring
• Tree-sitter for fast, accurate syntax highlighting
• Lua configuration and plugin API, with full Vimscript compatibility
• Asynchronous plugin architecture that never blocks the UI
• Embedded terminal emulator
• The vim command and config files still work as you expect

How it compares

Against Vim, Neovim is the more modern codebase: async plugins, LSP, and Lua are first-class rather than bolted on. Against GUI editors like VS Code it trades polished defaults for speed, scriptability, and a keyboard-first workflow. Against Helix it is more configurable, though that flexibility means spending time on setup.
