What is Claude Code?

Claude Code is Anthropic's official Agentic CLI programming assistant. It runs directly in the terminal and can understand the entire code base, modify code across files, execute tests, and handle Git workflows. Suitable for developers who want to complete complex programming tasks efficiently in a terminal environment.

Core Features

  • The terminal runs natively and supports natural language instructions to operate the code library.
  • Automatically modify cross-files and understand the overall context of the project
  • Automate tests, run commands and commit code
  • Supports IDE integration and GitHub @claude annotation triggering
  • Agentic mode: autonomously plan and complete multi-step programming tasks

Pricing Plans

You need to subscribe to Claude Pro ($20/month) or Max ($100/$200/month) to use it; API access method billed by Token is also supported.

Pros

  • Officially produced by Anthropic, with strong modeling capabilities (Claude Sonnet/Opus)
  • True Agentic programming to complete end-to-end tasks autonomously
  • Terminal native, no need to switch IDE, suitable for heavy command line users

Cons

  • No free version, high entry barrier
  • The Pro plan has a usage limit, heavy use requires upgrading to Max
  • Domestic network access is limited, so you need to surf the Internet scientifically

Claude Code is a terminal-native AI programming tool launched by Anthropic in 2025, built on the Claude Sonnet and Opus series models. Unlike inline completion tools such as GitHub Copilot, Claude Code is positioned as an agentic programming assistant - it does not just prompt the next line of code, but can understand the entire project structure and autonomously complete the complete workflow of “fix bugs → run tests → submit code”.
