Cursor is the AI-first code editor built by Anysphere on top of a VS Code fork. By bundling tab completion, chat, multi-file editing, and agentic composition into a single interface it became the most attention-grabbing alternative to GitHub Copilot through 2024–2025. It runs models like Claude Sonnet, GPT-5, and Gemini Pro under the hood. It is the practical face of the Vibe Coding and Agentic Coding wave, sitting at the heart of the developer-productivity debate.
