Claude Code
Definition
Claude Code is Anthropic’s AI-powered coding assistant. It brings Claude into the development workflow via terminal, IDE (VS Code, JetBrains), web, iOS, and Slack, with inline editing, diffs, and command-line tools.
It is similar to Cursor and GitHub Copilot in offering code generation and editing with LLM context; differentiation includes native terminal and multi-environment support (desktop, browser, IDE). Useful for agent-like workflows: explore codebases, apply changes, and get answers from the terminal or editor.
How it works
You run Claude Code from the terminal (CLI), inside an IDE (VS Code or JetBrains extension), or in the browser/iOS app. The model (Claude) has access to your project, open files, and terminal; you ask in natural language for edits, explanations, or refactors. Terminal: run commands to explore repos, generate code, or apply changes. IDE: use inline edits and visual diffs, then accept or reject. Context is managed by the tool (file selection, project scope). A Claude subscription (Pro, Teams, Enterprise) or access via Amazon Bedrock or Vertex AI is required.
Use cases
Claude Code fits developers who want Claude in the terminal and IDE with a single, multi-environment tool.
- Exploring codebases and answering questions from the command line
- In-IDE code generation, refactoring, and edits with visual diffs
- Cross-platform use (terminal, VS Code, JetBrains, web, mobile)
