Cursor
VS Code fork with deep AI integration — fastest-adopted AI IDE among developers
About
Cursor is an AI-first code editor built on VS Code that has become the most popular AI IDE among individual developers and startup engineering teams. Its Composer feature enables multi-file editing from natural language instructions, while its codebase-aware chat understands your entire repository. What sets Cursor apart is the quality of its AI integration — it feels like pair programming with a senior engineer who knows your entire codebase, rather than just autocomplete with extra steps. Key Features: Composer for multi-file AI edits from natural language | @codebase for asking questions about your entire repo | Tab autocomplete that predicts your next edit | Inline editing with diff view | Privacy mode so code never leaves your machine | Support for Claude, GPT-4, and other models | All VS Code extensions work natively Best For: Individual developers and small engineering teams who want the deepest, most capable AI integration in their code editor. Pros: Best multi-file editing experience available | Feels genuinely like pair programming | Privacy mode for sensitive code Cons: More expensive than GitHub Copilot | Can be slow with very large codebases | Occasional context window limitations on complex tasks
