Nev

Nev is a fast, keyboard-driven text editor written in Nim that runs in the terminal and in a GUI. It combines ideas from Neovim, Helix, and Zed with builtin developer tools like Git integration, Treesitter syntax highlighting, LSP support, DAP debugging, and WASM plugins.

I’m developing Nev for fun and only work on it in my free time. Use at your own risk!
