Amazon Nova Act extension: Build and test AI agents within your IDE

We’re excited today to announce the Amazon Nova Act extension - a tool that transforms how you build with Nova Act by bringing the entire agent development experience directly into IDEs like Visual Studio Code, Kiro, and Cursor. The Nova Act extension consolidates natural language based script creation, granular scripting precision, and robust browser testing into a single, unified user interface, eliminating the need to switch between multiple tools across development, validation, and iteration.

The Nova Act extension is built on top of the Nova Act SDK, available in research preview since March 2025. The Nova Act extension addresses feedback we have received from developers and consolidates the agent development lifecycle, from ideation to production, into one unified user interface within your IDE.

The Nova Act extension is available today from your IDE’s extension marketplace. The Nova Act GitHub repository includes documentation and examples to get started.
