The reference code editor: light, free, endlessly extensible, and now the default foundation for development.

Visual Studio Code (VS Code) has become the most widely used code editor in the world. Free and open source, built by Microsoft, it combines the lightness of a text editor with the power of a full development environment, thanks to a massive extension ecosystem.
VS Code is used to write, debug, and version code in nearly every language. It bundles a debugger, a terminal, Git management with GitHub, and syntax highlighting. Its real strength is extensions: one for every language, framework, or tool, installable in a click, turning the editor into a workshop built to order. IntelliSense completion assists you as you type.
Compared to full IDEs like JetBrains', VS Code is lighter and free, while specialized IDEs go deeper on a specific language. It has become the default foundation, including for AI coding assistants like Claude Code, which plug directly into it.
Piling on extensions can slow startup and raises questions of trust in their code. Microsoft's official build ships with telemetry, which pushes some users toward VSCodium, a version with no tracking at all. GitHub Copilot, the AI assistant, is a separate paid subscription.
