Cursor

Cursor is a code editor forked from VS Code that integrates LLM assistance at every level of the editing workflow. Unlike traditional code editors where AI is an add-on extension, Cursor treats AI as a first-class feature: you can describe changes to multiple files in natural language, ask questions about any code in the codebase, and apply AI-suggested edits with a single key press.

Key features include: Composer (multi-file editing from a single prompt), Chat (ask questions about the codebase), inline suggestions (like Copilot), and agent mode (the AI takes sequential actions to complete a larger task).

Cursor became the dominant editor for vibe coding workflows in 2024-2025. Because it is VS Code-compatible, all existing VS Code extensions, themes, and keybindings work without changes.
