Vibe Coding is a term popularized by Andrej Karpathy in a February 2025 tweet, describing the practice of letting AI write code from natural-language intent without the developer reading each line. "You see an error, paste it, the model fixes it," as Karpathy put it. Tools like Cursor, Claude Code, and Bolt brought this practice into daily routine and created real velocity for small projects and prototypes. Critics raise legitimate concerns about security, maintainability, and debt accumulation; even so, the term has become a defining symbol in the agentic-coding conversation.
