Claude Code
Anthropic's agentic CLI coding assistant with deep codebase understanding
From $20/mo
What is Claude Code?
Claude Code is Anthropic's agentic coding tool, released in 2024 as a CLI-based interface to the Claude family of models. Unlike IDE plugins that assist you as you type, Claude Code is designed for terminal-centric workflows where you describe a task in natural language and the agent executes it — reading files, writing code, running tests, and iterating until the task is complete. It is built on Claude's famously large context window, which means it can reason across entire codebases without losing track of distant dependencies and design decisions.
The key differentiator for Claude Code is the quality of its reasoning on complex, ambiguous tasks. Claude 3.5 and 3.7 Sonnet are widely regarded as among the best models for coding tasks, and Claude Code exposes that capability in an agentic format. It excels at tasks that require understanding the structure of a codebase, identifying the right places to make changes, and explaining its reasoning clearly — which makes it easier to review and trust its output compared to agents that just produce diffs without explanation.
Claude Code integrates directly with the terminal and can use tools like bash, grep, and git as part of its execution. It supports a permissions model where you can approve or deny specific actions before they execute, giving you fine-grained control over what the agent does on your system. The MCP (Model Context Protocol) server support allows Claude Code to connect to external data sources and APIs, extending its capabilities significantly for teams with custom tooling. Pricing is token-based through Anthropic's API, which makes cost predictable but requires an existing Claude API subscription.
