Visual Studio Code, usually called VS Code, is a source code editor made by Microsoft. It was announced in 2015 and is built on Electron. The core code is open source under the MIT license, and Microsoft ships its own branded build.
VS Code supports most programming languages through extensions. It has syntax highlighting, code completion, a built in terminal, debugging and Git integration. The extension marketplace adds language support, themes, linters, formatters and tools for databases, containers and cloud services. Remote development lets people edit code on a server, inside a container or in Windows Subsystem for Linux as if it were local. Settings Sync keeps extensions and preferences the same across machines.
VS Code is free to download and use. It runs on Windows, Mac and Linux, and vscode.dev offers a lighter version in the browser. GitHub Codespaces uses it as the editor for cloud development environments. Several other editors, including Cursor and VSCodium, are built on its open source code. In developer surveys it is the most used code editor by a wide margin, among both students and professional programmers.
