## Intro

Visual Studio Code is Microsoft open-source code editor built on the Electron framework. First released in 2015 at Build conference, VS Code quickly became the dominant code editor, overtaking Sublime Text, Atom, and eventually Notepad++. Combines lightweight startup and extensibility with a rich feature set: IntelliSense, integrated debugging, Git, terminal, and a 60,000+ extension marketplace.

- **Repo**: https://github.com/microsoft/vscode
- **Stars**: 183K+
- **Language**: TypeScript
- **License**: MIT (source) / proprietary (Microsoft branded build)

## What VS Code Does

- **IntelliSense** — smart completions with type info
- **Debugging** — launch and debug Node, Python, Go, C++, etc.
- **Git integration** — inline diff, stage, commit, push
- **Extensions** — 60,000+ on marketplace
- **Integrated terminal** — shell inside editor
- **Multi-cursor** — Ctrl+D to add cursor to next match
- **Live Share** — real-time pair programming
- **Remote development** — SSH, containers, WSL, Codespaces
- **Jupyter notebooks** — built-in support
- **Task runners** — define tasks.json for project commands
- **Workspace settings** — per-project and user config

## Architecture

Electron shell + Monaco editor (the web-based component also used in monaco-editor). Language features delegated to Language Servers via the Language Server Protocol (LSP, originally invented for VS Code). Extensions run in a separate Extension Host process for isolation.

## Self-Hosting

The source code at `microsoft/vscode` is MIT-licensed, but the branded "Visual Studio Code" binary includes proprietary telemetry and the Microsoft Marketplace. Open-source builds:
- **VSCodium** — no telemetry, community build
- **Code - OSS** — the raw open-source build
- **Cursor** — AI-first VS Code fork
- **Windsurf** — another AI-first fork

## Key Features

- Free and open source (core)
- Cross-platform
- Extensive marketplace
- LSP-based language features
- Integrated Git, terminal, debugger
- Remote development (SSH, containers, WSL)
- Live Share
- Profiles (per-language setups)
- Jupyter notebook support
- Settings Sync

## Comparison

| Editor | Extensibility | Remote Dev | AI Focus |
|---|---|---|---|
| VS Code | Marketplace | Best | Copilot + extensions |
| Cursor | VS Code fork | Same | AI-first |
| Windsurf | VS Code fork | Same | AI-first |
| JetBrains IDEs | Plugins | Gateway | AI Assistant |
| Zed | Native | Yes | Built-in |
| Sublime Text | Python packages | Limited | Via plugins |

## FAQ

**Q: What is the difference between VS Code and VS Codium?**
A: VS Codium is a rebuild of Microsoft's VS Code source with branding and telemetry removed. Functionally identical with better privacy, but it cannot use the MS Marketplace (switch to the Open VSX Registry).

**Q: What Remote Development options exist?**
A: Remote - SSH (remote server), Dev Containers (Docker containers), WSL (Windows Subsystem for Linux), and Codespaces (hosted). The editor runs locally while the language server and files stay remote.

**Q: Compared to JetBrains?**
A: VS Code starts fast, is free, has many extensions, and is language-agnostic; JetBrains goes deeper for specific languages (Java/Kotlin/Go/Rust) and has smarter refactoring.
