Open-source Sublime Text alternatives

This repository, known as Code - OSS, is where Microsoft develops Visual Studio Code together with the community. Visual Studio Code is a code editor that pairs the simplicity of a lightweight editor with the tools developers need to edit, build and debug, and it runs on Windows, macOS and Linux. Roadmap and iteration plans are published alongside the code.

Main capabilities include code editing, navigation and code understanding support, lightweight debugging and integration with existing tools. A rich extension model lets people add languages, themes and tooling. The editor is built with TypeScript on Electron and is updated monthly, with a daily Insiders build for those who want the newest changes.

The source code is available under the MIT license. The downloadable Visual Studio Code product is a distribution of this repository that adds Microsoft-specific customizations and ships under a traditional Microsoft product license. That distinction matters for anyone who wants to build a fully open-source editor straight from the repository.

Neovim is a text editor that refactors Vim to simplify maintenance, encourage contributions, split work among several developers, and allow advanced user interfaces without changes to the core. Most Vim plugins work with it, as do Ruby and Python-based ones, so existing setups largely carry over.

Key features include modern GUIs, an API that can be accessed from many languages such as C, Go, JavaScript, Python, Lua and Rust, a terminal emulator embedded in the editor and open to scripting, asynchronous job control, data shared across multiple editor instances, and support for XDG base directories. The full feature list is available in the built-in help.

Pre-built packages are provided for Windows, macOS and Linux, and many distributions package it, including Homebrew, Debian, Ubuntu, Fedora and Arch Linux. It can also be built from source with CMake. The README includes guidance for moving over from Vim. GitHub lists the license as 'Other', so check the repository for details. It suits developers and writers who like modal editing and want a scriptable editor.

Zed is a code editor built for speed and for editing together with other people, created by the team behind Atom and Tree-sitter. It is written in Rust and available for macOS, Linux and Windows, with a web version still only under discussion. It is developed by Zed Industries, a for-profit company.

The code is mostly GPL-3.0-or-later, with some Apache-2.0 components that are labeled as such, and the project uses tooling to keep third-party license information correct. Installation is by direct download or through local package managers on each platform, and the repository documents how to build Zed for each operating system.

Zed suits developers who want a fast native editor with collaboration built in and are comfortable with a GPL-licensed codebase. Sponsorship donations through GitHub Sponsors go directly to the company, and contributions are welcome through the guidelines in CONTRIBUTING.md.

Helix is a modal text editor written in Rust and inspired by Kakoune and Neovim. Its editing model is heavily based on Kakoune, whose design decisions the author largely agreed with while building it. It is released under the MPL-2.0 license and is primarily a terminal-based editor.

It offers modal editing in the Vim style, several simultaneous selections, language server support out of the box, and incremental syntax highlighting and code editing built on tree-sitter. The author has said they may explore a custom wgpu-based renderer, along the lines of Emacs. Shortcuts and keymaps are documented on the project website.

The README notes that only certain languages currently have indentation definitions. Installation instructions, a FAQ and a community Matrix space are linked for help. Helix suits developers who like modal editing and want language tooling that works out of the box without assembling many plugins.

Vim is an enhanced descendant of the classic UNIX editor Vi. It adds spell checking, syntax highlighting, filename completion, block operations, a command history, online help, a scripting language and multi-level undo, and a graphical interface is also available. Vi compatibility is maintained, so people who learned Vi feel at home. This is the official repository, and the license is Vim's own.

It works well for source code and other plain text. Commands are typed with ordinary keyboard characters, which lets fast typists work quickly, while function keys can be mapped to commands and the mouse can be used. It can also be built with a minimal feature set, usually called vim.tiny, to act as a largely POSIX-compatible vi, which many Linux distributions ship as their default vi.

Vim runs on Windows, macOS, Haiku, VMS and almost all flavors of UNIX, and older versions ran on systems such as MS-DOS and Amiga that are no longer maintained. Vim9 script is documented separately. On Mac and Linux a small version is often preinstalled, and package managers provide fuller builds. It suits developers, system administrators and writers who edit text from the keyboard.

VSCodium is a repository of scripts that automatically build Microsoft's open-source vscode source code into freely licensed binaries with a community-driven default configuration. The maintainers stress that it is not a fork. The result is a code editor and IDE that feels like Visual Studio Code but drops the Microsoft branding, telemetry and the licensing terms of Microsoft's own distribution.

Releases come as stable and insiders builds and can be installed through Homebrew, WinGet, Chocolatey, Scoop, Snap, Flatpak, the Arch User Repository, or apt, dnf and zypper repositories, as well as deb, rpm and tar downloads. The build scripts are written in Shell and published under the MIT license, so anyone can inspect how the binaries are produced. Extensions are a common area of difference, so review the project's notes before relying on a specific one.

Notepad++ is a free source code editor that also works as a replacement for the built-in Windows Notepad. It supports a number of programming languages and natural languages, and runs in the Microsoft Windows environment. The README describes it as free in both senses of the word, and says its use is governed by the GPL. It is written in C++.

The project supports all Windows systems that Microsoft still supports, and publishes a page of supported-system information for users who run older versions. Releases since version 7.6.5 have been signed with GPG, and the README publishes the signing key details so that downloads can be verified. Build instructions are provided for people who want to compile it from source, and contributions are welcome under the project's contribution rules. Further details are on the official site.

GNU Emacs is an extensible, customizable, free text editor. The editor is built around an Emacs Lisp interpreter, a Lisp variant extended for editing text, and that same language is used to customize and extend it, which makes nearly every behavior of the editor programmable by its users.

Emacs offers content-aware editing modes with syntax coloring for many file types, built-in documentation with a tutorial for new users, and full Unicode support. It doubles as a calendar, an IRC client, a news and mail reader, a project planner and a front end for debuggers, and a packaging system downloads and installs extensions.

Emacs runs on GNU/Linux, the BSDs, Haiku, Windows, macOS and Android, and is licensed under GPL-3.0. Customization is done with Emacs Lisp code or a graphical interface. The GitHub repository is a mirror of the GNU project's source, and the official site offers downloads, a guided tour and documentation.
