Claude Code and Cursor represent two distinct approaches to AI-assisted software development, catering to different user preferences and development environments. Claude Code is a CLI-first coding assistant that operates within the terminal, allowing for extensive automation and multi-file editing by executing shell commands through a lightweight large language model (LLM). It thrives in environments where developers work with tmux panes and Git branches, offering headless automation, full-repository refactors, and the ability to integrate with various tools and workflows. In contrast, Cursor is an AI-enhanced code editor built on a VS Code fork, providing a rich graphical interface focused on inline, single-file edits with support for multiple model providers. Users of Claude Code are encouraged to adopt a meticulous plan-before-code workflow, ensuring precise execution by iterating on a detailed text plan before implementation. Advanced techniques for maximizing productivity with Claude Code include parallel execution with Git worktrees, automated plan-review-execute cycles, and the use of voice control for hands-free coding. Observability tools, like Dev-Agent-Lens, help monitor the performance and efficiency of Claude Code operations, providing insights into prompt sizes and token costs.
