Claude Code runs on macOS 13.0 or newer, Windows 10 version 1809 or newer (or Windows Server 2019+), and Linux distributions including Ubuntu 20.04+, Debian 10+ and Alpine Linux 3.19+, on a machine with at least 4 GB of RAM and an x64 or ARM64 processor, according to Anthropic’s official setup documentation.
As of November 10, 2026, Claude Code also needs an internet connection, a Bash, Zsh, PowerShell or CMD shell, and use from an Anthropic-supported country. It requires a Pro, Max, Ultra, Team, Enterprise or Console account; the free Claude.ai plan does not include Claude Code. It can also be used through Amazon Bedrock, Google Cloud or Microsoft Foundry.
The native installer does not need Node.js, but the npm package requires Node.js 22 or later. On native Windows, Git for Windows is recommended so Claude Code can use its Bash tool. Git is otherwise optional.
