discontinued Archived on December 15, 2022. After Microsoft acquired GitHub in 2018, Atom became redundant alongside VS Code — which used the same Electron framework but had faster performance, better extension ecosystem, and full corporate backing. Atom's slow startup and memory issues drove users away long before the official sunset.

Neovim

Vim

open sourceexplicit relation

Vim is a highly configurable terminal text editor that has been a cornerstone of Unix and Linux development for over three decades. Built as an improved version of vi, Vim solves efficient text manipulation through its modal editing paradigm — separating insert and command modes so that keystrokes become powerful composable operations. Extensive plugin ecosystem, scripting via Vimscript/Lua, and first-class support in nearly every system.

100% free and open source ($0) Charityware under the GPL-compatible Vim License. Available across all Unix/Linux, macOS, and Windows systems with zero commercial licensing fees (users are encouraged to donate to ICCF Holland to support orphans in Uganda).
