Visual Studio Code (VS Code) is a free, open-source code editor built by Microsoft. It's the single most-used development tool in the world, with roughly 75.9% of developers reporting they use it — a lead no other editor or IDE comes close to. Its popularity comes from being fast and lightweight out of the box, while a massive extension marketplace lets it become a full-featured environment for almost any language or stack.
📌 Quick facts
Type: Lightweight, extensible code editor
Made by: Microsoft
License: Free, open-source (MIT-licensed core; the official Microsoft build adds some proprietary telemetry/branding)
Platforms: Windows, macOS, Linux, and a browser version (vscode.dev)
Primary use case: General-purpose coding across nearly every language, from web dev to Python to DevOps scripting
Key features
- Huge extension marketplace — thousands of extensions add language support, linters, themes, and entire toolchains
