Anthropic's terminal-based coding agent that edits and runs your project
Claude Code is Anthropic's agentic coding tool. Instead of suggesting the next line, it works inside a project: reading files, planning a change, editing across several files, running tests and committing to git, then reporting what it did. It runs mainly from the terminal, with IDE extensions and browser or mobile options for starting and reviewing sessions. It follows project conventions through a memory file, can call external tools through MCP servers, and supports hooks for automating workflow steps. The differentiator is depth of autonomy, since it is built for multi-step tasks in an existing codebase rather than inline completion.

Autocomplete predicts the next lines as you type. Claude Code takes a task, reads the relevant files, plans the change, edits several files, runs commands and reports results, which suits work spanning a whole feature.
Yes, effectively. It is included with paid Claude plans and also works on API credits, but there is no lasting free tier. Usage limits depend on the plan you hold.
By default it asks before running commands or writing files, and permission settings let you allow or block whole categories of action. Most teams keep review in the loop for anything touching production code.
