Claude Code is an agentic coding tool that reads your codebase, edits files, and runs commands. It works in your terminal, IDE, browser, and as a desktop app.

​
Get started

Choose your environment to get started. Most surfaces require a Claude subscription or Anthropic Console account. The Terminal CLI and VS Code also support third-party providers.
The full-featured CLI for working with Claude Code directly in your terminal. Edit files, run commands, and manage your entire project from the command line.To install Claude Code, use one of the following methods:Then start Claude Code in any project:
cd your-project
claude
You’ll be prompted to log in on first use. That’s it! Continue with the Quickstart →
See advanced setup for installation options, manual updates, or uninstallation instructions. Visit troubleshooting if you hit issues.

What you can do

Here are some of the ways you can use Claude Code:
Claude Code handles the tedious tasks that eat up your day: writing tests for untested code, fixing lint errors across a project, resolving merge conflicts, updating dependencies, and writing release notes.
claude "write tests for the auth module, run them, and fix any failures"
Describe what you want in plain language. Claude Code plans the approach, writes the code across multiple files, and verifies it works.For bugs, paste an error message or describe the symptom. Claude Code traces the issue through your codebase, identifies the root cause, and implements a fix. See common workflows for more examples.
Claude Code works directly with git. It stages changes, writes commit messages, creates branches, and opens pull requests.
claude "commit my changes with a descriptive message"
In CI, you can automate code review and issue triage with GitHub Actions or GitLab CI/CD.
The Model Context Protocol (MCP) is an open standard for connecting AI tools to external data sources. With MCP, Claude Code can read your design docs in Google Drive, update tickets in Jira, pull data from Slack, or use your own custom tooling.
CLAUDE.md is a markdown file you add to your project root that Claude Code reads at the start of every session. Use it to set coding standards, architecture decisions, preferred libraries, and review checklists.Create custom slash commands to package repeatable workflows your team can share, like /review-pr or /deploy-staging.Hooks let you run shell commands before or after Claude Code actions, like auto-formatting after every file edit or running lint before a commit.
Spawn multiple Claude Code agents that work on different parts of a task simultaneously. A lead agent coordinates the work, assigns subtasks, and merges results.For fully custom workflows, the Agent SDK lets you build your own agents powered by Claude Code’s tools and capabilities, with full control over orchestration, tool access, and permissions.
Claude Code is composable and follows the Unix philosophy. Pipe logs into it, run it in CI, or chain it with other tools:
# Monitor logs and get alerted
tail -f app.log | claude -p "Slack me if you see any anomalies"

# Automate translations in CI
claude -p "translate new strings into French and raise a PR for review"

# Bulk operations across files
git diff main --name-only | claude -p "review these changed files for security issues"
See the CLI reference for the full set of commands and flags.
Start a task on your laptop and pick it up on your phone. Claude Code on the web and the Claude iOS app run sessions on cloud infrastructure, so you can kick off work from anywhere without a local dev environment.You can also route coding tasks straight from team chat: mention @Claude in Slack with a bug report or feature request, and get a pull request back.

​
Use Claude Code everywhere

Each surface connects to the same underlying Claude Code engine, so your CLAUDE.md files, settings, and MCP servers work across all of them. Beyond the Terminal, VS Code, JetBrains, Desktop, and Web environments above, Claude Code integrates with CI/CD, chat, and browser workflows:
