Cursor

Cursor is the fastest-growing AI-native code editor, built as a VS Code fork with AI deeply embedded into every aspect of the editing experience. Rather than bolting AI onto an existing editor, Cursor was designed from the ground up around AI-assisted workflows including tab completion, inline editing, multi-file changes, and autonomous agent mode.

Cursor's standout features include Cmd+K for inline code generation and editing, a chat interface with full codebase context, and Composer for multi-file autonomous changes. It supports multiple AI models including GPT-4, Claude, and its own fine-tuned models, letting developers choose based on their preference. The editor understands your entire project through codebase indexing and can reference documentation, past conversations, and specific files.

The agent mode (Composer Agent) can autonomously implement features across multiple files, run terminal commands, and iterate on errors. It handles tasks like adding new API endpoints, refactoring modules, and writing tests with minimal human intervention. Privacy-conscious users can enable Privacy Mode to ensure code is never stored on Cursor's servers.

With reported 56% month-over-month traffic growth and a rapidly expanding user base, Cursor has become the default choice for developers who want AI as a first-class citizen in their editor. Its VS Code compatibility means most extensions and keybindings work seamlessly.
