# AWS previews the Amazon Nova Act SDK

> AWS announced a preview of the Amazon Nova Act SDK for building browser automation agents. The company said the SDK used a Nova Act model fine-tuned for browser execution and included integration with IAM credential management, Amazon S3 data controls, and a browser tool. AWS positioned the release around multi-step browser workflows, Python scripting, and testing or debugging agent behavior before deployment.

## Engineering relevance

Browser automation increases the chance that an AI workflow crosses from reading to acting in a third-party system. The release makes identity, storage, browser state, and human intervention first-class design concerns. A browser agent can be useful without being autonomous: each workflow needs explicit permitted actions, test coverage, error handling, and an accountable owner for its effects.

## Preview capability

AWS described the Nova Act SDK as a preview for browser automation agents built with Python and natural-language instructions. The company said the model was designed for browser execution and connected the SDK to IAM credential management, S3 data controls, and the Genesis Browser Tool.

## Workflow focus

The announcement used dynamic multi-step browser tasks, such as form and portal workflows, to explain the product's focus. AWS said developers could integrate scripts into codebases and CI/CD pipelines, debug workflows, and direct browser control where needed. Those controls are product features, not a substitute for application-specific authorization design.
