Visual Studio Code is a free, open source code editor from Microsoft that runs on Mac, Windows, and Linux. It's built for developers who want a lightweight editor with AI agents that can take on coding tasks.

Key features:

Hand off tasks to AI agents that plan, make code changes, run commands, and iterate until the job is done.
Run CLI-based agents in the background, work with an agent using live validation in the integrated browser, or delegate to a cloud agent that opens a pull request.
Keep several agent sessions running and switch between them from a sessions list.

VS Code is a free download for macOS, with Insiders and web editions also available.
