# Best Open-Source Code Editors and IDEs in 2026

Source: https://listme.name/best/code-editors-and-ides/open-source

Code editors split into full IDEs that understand one language stack in depth, general editors that cover many languages, and terminal editors for keyboard-first work. This ranking favors free tools that run on several systems, then weighs deeper IDE support for specific stacks.

## 1. Visual Studio Code (score 94.5)

Free, widely used and extensible, with an integrated terminal, Git tools and a large extension marketplace. Its source is MIT-licensed on GitHub, though the official build uses Microsoft's product license.

- Best for: Multi-language work in one free editor
- Free | Windows, macOS, Linux, Web | open source (MIT)

## 2. Zed (score 88.0)

A fast editor with multiplayer editing included in every plan, and a free Personal plan. AI features need Pro or your own API keys, and the Business plan is priced per seat.

- Best for: Fast editing with built-in collaboration
- Free plan, paid upgrades | macOS, Linux, Windows | open source (GPL-3.0)

## 5. GNU Emacs (score 81.5)

GNU Emacs is GPL-3.0 free software that runs on GNU/Linux, BSDs, Windows, macOS and Haiku, configured in Emacs Lisp. It is extensible in ways few editors match, but its learning curve is steeper than Zed or VS Code.

- Best for: Long-lived, highly customized editing in Lisp
- Free and open source | Linux, macOS, Windows | open source (GPL-3.0)
