Google Antigravity vs Cursor: Which AI IDE is Right for You in 2025?

The AI-powered IDE landscape has exploded in 2025, with two major players dominating the conversation: Google Antigravity and Cursor. Both promise to revolutionize how we write code, but which one should you choose? In this comprehensive comparison, we'll dive deep into features, performance, pricing, and real-world usage to help you make an informed decision.

The Story Behind Each IDE

Google Antigravity: The Enterprise Powerhouse

Launched in early 2025, Google Antigravity emerged from Google's internal developer tools team. Originally built to accelerate development within Google's massive codebase, Antigravity was designed from day one to handle enterprise-scale projects with millions of lines of code.

Key Philosophy: "AI that understands your entire system, not just your current file."

Cursor: The Pioneer of AI-Native Development

Cursor, founded by former OpenAI and Meta engineers, pioneered the concept of building an IDE from scratch with AI at its core rather than bolting AI features onto existing editors. Since its 2023 launch, Cursor has focused on making AI-powered development feel natural and intuitive.

Key Philosophy: "The IDE should feel like pair programming with the world's best developer."
