Quick answer: Anthropic's coding agent — terminal-native, deeply context-aware.
Claude Code is Anthropic's terminal-native coding agent, designed to assist developers directly from the command line. Built by Anthropic, the creators of Claude, it integrates AI capabilities into your IDE workflow while maintaining deep context awareness of your entire codebase. Unlike traditional code editors, Claude Code runs as a CLI tool that can read files, execute bash commands, and modify code—all while understanding the broader structure and dependencies of your project. It falls under the IDE category and is available through Claude Pro, Claude Team, and the Claude API, making it accessible for individual developers and teams alike.
