Three AI Coding Assistants: Understanding Your Options

This practical comparison evaluates GitHub Copilot, Cursor, and Claude Code based on real production usage, revealing that each tool excels in different contexts. While Copilot dominates single-file automation through intelligent tab-completion, Cursor provides multi-file project awareness within a VS Code-based IDE, and Claude Code functions as a terminal agent for autonomous, complex tasks. Understanding these distinctions is critical because the right tool can dramatically accelerate development workflows, while the wrong choice wastes both money and productivity.
