Neovim

Neovim is a Vim fork built for people who want Vim's editing model without its limitations. It keeps full compatibility with Vimscript and Vim 8 plugins while adding a modern foundation underneath. If you already live in Vim, switching is low-friction. If you're new to modal editing, :Tutor gets you started.

The core philosophy is extensibility without bloat. Neovim's codebase is roughly 30% smaller than Vim's, yet it adds capabilities that Vim lacks entirely.

What makes it different from Vim:

• Lua configuration replaces the need for Vimscript. Your entire config can live in init.lua, and plugins can be written in any language that speaks the remote API.
• Built-in LSP client gives you go-to definition, find references, rename, and code formatting without installing a separate plugin manager or language server shim.
• Tree-sitter integration produces an AST for fast, accurate syntax highlighting and enables text objects and motions that understand code structure, not just patterns.
• Async plugin architecture runs remote plugins as co-processes, so slow plugins can't freeze the editor.
• Client-server model lets you attach multiple UIs to a single Neovim session, similar to tmux but built into the editor itself.
• Embeddable as a component: GUIs, IDEs, and web browsers can embed Neovim directly. There's even a UI that runs it inside VS Code or a browser.

Neovim targets terminal power users, developers who want a fast editor that pairs well with tools like Alacritty, and anyone building editor tooling or custom UIs on top of a capable core. It works identically across platforms with a single build type and a single command.
