Buyer's question

What Is Claude Code? Anthropic's terminal-based coding assistant.

A practical explainer of Claude Code — what it is, who it's for, and how it differs from Cursor and other AI coding tools. For technical leaders evaluating AI coding tools in 2026.

Short answer

Claude Code is Anthropic's command-line AI coding tool — an agent that runs in your terminal, reads your codebase, runs commands, edits files, and ships code with you. It's used by engineering teams who want AI assistance integrated deeply into their existing dev workflows, especially in larger codebases where context matters.

What it does

Claude Code runs in your terminal. You give it tasks ("add a new endpoint to the API," "refactor this function," "fix this failing test") and it reads relevant files, makes edits, runs tests, and reports back. You stay in control — every meaningful action surfaces for your review or auto-approval.

Unlike IDE-based AI tools (Cursor, GitHub Copilot), Claude Code is shell-native. It uses the same Bash, Git, build tools, and test runners you already use. It's particularly strong for multi-file changes and long-context reasoning across large codebases.

FAQ

Is Claude Code free?

Claude Code requires a Claude subscription (Pro, Team, or Enterprise) or API access. The tool itself is free to install.

Does Claude Code work without internet?

No — it requires API access to Claude. The local agent shells commands locally but the model lives in the cloud.

Can Claude Code see my entire codebase?

It reads files as needed for the task. It does not upload your entire codebase unconditionally. You control which files and folders are in scope.

Is Claude Code safe to run on production code?

It can run on production code, but follow standard safety: work in a feature branch, review every change, keep tests passing. Treat it like a junior engineer you trust but verify.

Should I use Claude Code or Cursor?

Both are excellent. Use Claude Code if you prefer terminal workflows or work in large codebases; Cursor if you prefer IDE workflows or rely heavily on inline autocomplete.
