Vim, or "Vi IMproved", is an advanced text editor that provides a myriad of features including syntax highlighting, word completion, and a vast amount of contributed content. This tool comes with a GUI version known as GVim. Vim's top features include being lightweight, keyboard-focused, and customizable. It supports a wide range of operating systems such as Mac, Windows, Linux, BSD, Haiku, AmigaOS, OpenSolaris, and MorphOS. Vim is recognized as an open-source software and is available for free.
In comparison to Visual Studio Code, Vim presents itself as a viable alternative. Both being Text Editor & Code Editors, they share some similar features such as customizability. However, Vim stands out with its lightweight design and keyboard-focused operation. Vim has received positive comments as an alternative to Visual Studio Code, with users noting it as 'the lightest alternative with the most features', praising its readiness to work as soon as it is opened, and its massive amount of extendable, open-source plugins.
