Claude Code is an agentic coding tool developed by Anthropic. It operates directly in a developer's terminal and integrates with IDEs, desktop apps, and browsers. Claude Code understands the entire codebase and assists with development tasks using natural language commands. It aims to simplify workflows by helping with refactoring, documenting, and debugging code efficiently.
Key features include editing and refactoring, bug fixing, code understanding, automated testing & linting. It can automate repetitive tasks like code formatting, running tests, and security checks. Claude Code also connects to external tools, databases, and APIs via the Model Context Protocol (MCP). Recent updates include agent teams, improved interactive usability, optional response-language settings, and expanded customization and control.
Claude Code is available through a few different subscription plans. Anthropic offers a free plan with limited daily messages. The Pro plan costs $20 per month (or $17 if billed annually). The Max plan has two tiers, at $100/month and $200/month, offering increased usage. There are also Team and Enterprise plans available.
