Cursor

Cursor is the AI-first IDE that puts AI at the center of the development experience rather than as a plugin. Built as a VS Code fork, it offers seamless familiarity with powerful AI capabilities. Agent Mode works autonomously—creating files, making architectural decisions, and executing terminal commands until tasks are complete. Composer Mode enables chat-based multi-file editing with automatic updates across the entire project. The new Shadow Workspace (2026) runs a background instance to verify generated code compiles before presenting it. Cursor indexes your entire codebase for deep context understanding. Pro ($20/mo) includes model access to Claude 3.7, GPT-5, and Gemini. Teams ($40/user/mo) adds shared rules and analytics.
