What Developers Say

"Cursor is at least a 2x improvement over Copilot. It's amazing having an AI pair programmer, and is an incredible accelerator for me and my team." - Ben Bernard, Instacart

"The Cursor tab completion while coding is occasionally so magic it defies reality - about ~25% of the time it is anticipating exactly what I want to do." - Kevin Whinnery, OpenAI

"Cursor is hands down my biggest workflow improvement in years" - Sawyer Hood, Figma

"Cursor is the best AI developer tool right now, avoid it at your own peril" - Logan Kilpatrick, Google
