by Anthropic · Best overall coding agent

Also known as Claude Code AI

Claude Code is Anthropic's agentic coding tool that works in your terminal, IDE, and the web. It reads entire codebases, edits files, runs tests, and completes multi-step engineering tasks autonomously. Included with Claude Pro ($20/month) and Max plans, it has become the default agent for many professional developers.

How Claude Code works

Claude Code is Anthropic's own agentic coding tool, and it has quietly become the default for a large share of professional developers. Rather than living inside a single editor, it runs in your terminal, plugs into IDEs through extensions, and also works on the web and in CI. You point it at a repository and describe a task; it reads the relevant files, plans a sequence of edits, runs tests and shell commands, reads the output, and keeps going until the task is done or it needs your input.

What sets it apart is long-horizon autonomy. Where many tools shine on a single function, Claude Code is built to hold an entire codebase in working memory and carry a multi-step task — a refactor that touches a dozen files, a migration, adding test coverage across a module — through to a working, tested result. It curates its own context, so you rarely have to manually paste files in, and it self-corrects when a test fails or a build breaks.

It is included with Claude Pro at $20/month and the higher Max plans, with usage-based API pricing for teams that automate it in CI. The main trade-offs are practical: heavy autonomous sessions can hit plan rate limits, and the terminal-first workflow takes some adjustment if you are used to a graphical assistant. For developers comfortable in a shell, it is the most capable hands-off agent available.

What people use Claude Code for

Large refactors across a codebase

Hand it a refactor that spans many files and let it edit, run tests, and fix its own regressions until the suite passes.

Backfilling test coverage

Ask it to write tests for an under-covered module; it explores the code, drafts cases, and iterates until they run green.

Automating engineering in CI

Wire it into pipelines via the API to handle routine fixes, dependency bumps, and migrations without a human in the loop.

Claude Code FAQ

What is Claude Code AI?

Claude Code AI is a colloquial way of referring to Claude Code — the product name has no "AI" in it. It's Anthropic's agentic coding tool: it runs in your terminal, IDE, and CI, reads entire codebases, edits files, runs tests, and completes multi-step engineering tasks autonomously. It's included with Claude Pro at $20/month and the Max plans.

How much does Claude Code cost?

It is included with Claude Pro at $20/month and with the higher Max plans, so most individual developers pay nothing extra beyond their Claude subscription. Teams that run it heavily through the API pay usage-based pricing on top.

Is Claude Code just for the terminal?

No. It started terminal-native but now also runs through IDE extensions, on the web, and in CI environments. The terminal remains the most powerful surface, but you are not limited to it.

How is Claude Code different from Cursor?

Cursor is an IDE you supervise edit-by-edit; Claude Code is built for hands-off, long-running tasks you delegate and review afterward. Many developers use Cursor for interactive work and Claude Code for autonomous jobs.

Can Claude Code work on a large existing codebase?

Yes — that is its strongest area. It reads and reasons over entire repositories without you manually selecting context, which is why it handles multi-file refactors and migrations better than most assistants.
