What Is Cursor?
What Is Aider?
A well-regarded project with 21k+ stars, Aider has proven itself in production deployments. Best suited for developers who want AI assistance integrated directly into their workflow rather than switching to a chat interface. The context window size limits its usefulness for very large codebase refactoring tasks.
