About Claude Code
Claude Code is Anthropic's AI-powered coding assistant built for professional developers. Unlike a chat-based tool, it operates directly inside your workflow -- in your terminal, IDE, desktop app, or browser -- with access to your actual codebase. It reads files, runs commands, writes and edits code across multiple files, creates commits, opens pull requests, and connects to external tools via MCP. You can spawn multiple sub-agents to work on parallel tasks simultaneously, schedule recurring jobs, and pipe it into CI/CD pipelines. Supported surfaces include the Terminal CLI (Mac, Windows, Linux), VS Code, JetBrains, Cursor, a standalone Desktop app, and the web.
Key Features
- Terminal CLI — Full-featured command-line interface for Mac, Windows, and Linux; reads files, runs commands, edits code, creates commits and PRs
- IDE Extensions — Native extensions for VS Code, Cursor, and JetBrains with inline diffs, plan review, and @-mention context sharing
- Desktop App — Standalone app for visual diff review, parallel sessions, and scheduling recurring tasks without an IDE
- Multi-Agent — Spawn parallel sub-agents that work on different parts of a task simultaneously, coordinated by a lead agent
- MCP Integration — Connect Claude Code to any external data source or tool via Model Context Protocol (Jira, Slack, Google Drive, custom APIs)
- CLAUDE.md — Add a markdown file to your project root with coding standards and preferences; Claude reads it every session
- Skills & Hooks — Package repeatable workflows (like /review-pr) as shareable skills; run shell commands before or after any action
- CI/CD Integration — Automate code review, issue triage, and PR creation via GitHub Actions and GitLab CI/CD pipelines
Pricing Structure
- Free — $0/month — Limited usage via a free Claude.ai account; includes CLI, VS Code and JetBrains extensions, and web access
- Pro — $20/month — Full Claude Code access across all surfaces including Desktop app, more usage, and access to all Claude models
- Max — From $100/month — 5x or 20x more usage than Pro for heavy Claude Code workflows; recommended for daily professional use
- API — Pay per token — Usage-based access via Anthropic Console; ideal for CI/CD pipelines, custom agents, and scripted automation
Why People Use It
Claude Code is one of the most capable agentic coding tools available because it operates directly in your development environment rather than alongside it. It understands your full codebase, not just a snippet, and can carry out multi-step tasks end to end -- from reading the error to writing the fix to running tests to opening the PR. The MCP integration and multi-agent support make it especially powerful for complex, real-world projects.
