Reviewers mostly praise Claude Code for handling real, complex software work rather than just autocomplete: they say it keeps track of large codebases, reasons through multi-file changes, writes cleaner code, and speeds up prototyping, debugging, refactoring, and shipping. Users add that it works best when given clear requirements, solid tests, and experienced guidance. The strongest criticisms are narrower: a learning curve to use it well, weaker performance on some frontend and framework-specific edge cases, and requests for deeper environment integration and more autonomous workflows.
