With MCP (Model Context Protocol) and multi-model support, developers can use AI models like Claude Sonnet, GPT-4, or Gemini—or connect their own keys via OpenRouter or Azure OpenAI. Deep GitHub integration, remote development, and cloud portability make collaboration effortless across global teams. VS Code’s extensive marketplace offers tens of thousands of extensions—from Docker to Jupyter and Stripe—empowering developers to build and deploy in any environment. Custom profiles, themes, and settings sync allow for a personalized workspace across devices. Its integrated terminal, local history, and debugging tools ensure smooth workflows from prototype to production. Whether building enterprise software, web apps, or AI agents, VS Code redefines what a modern coding experience should feel like: intelligent, fast, and universally accessible.
