Amazon Nova Act

Amazon Nova Act

Amazon Nova Act is AWS's agent for driving software that has no API. Nova Act completes repetitive UI workflows in a browser and escalates to a human supervisor when a step needs a decision, which is the design detail that separates a production automation from a demo. It is powered by a custom Nova 2 Lite model, reached through an SDK and a playground, and it plugs into the AWS machinery teams already run — Bedrock AgentCore, CloudWatch and IAM.

Production credibility: Nova Act reached general availability in December 2025 after a research preview, so write-ups describing it as a preview are out of date. It is on the AWS HIPAA Eligible Services list, works with the Strands Agents framework, and was initially offered in US East (N. Virginia), with region coverage published by AWS. Developers obtain an API key at nova.amazon.com/act. Billing follows AWS consumption rather than a seat price.

Key Features

• Browser automation of repetitive UI workflows
• Escalation to a human supervisor when a step needs judgment
• Powered by a custom Nova 2 Lite model
• Integrations with Bedrock AgentCore, CloudWatch and IAM
• Works with the Strands Agents framework
• HIPAA-eligible, with an SDK and a browser playground

Ideal Use Case

Back-office processes that live in a vendor portal with no API: claims entry, order processing, account maintenance. The supervisor escalation makes it suitable in regulated settings where an agent that guesses is worse than one that stops, and HIPAA eligibility matters for healthcare operations teams.

How Amazon Nova Act differentiates

Browser Use, Skyvern and Stagehand are open frameworks you assemble and host. Nova Act is a managed AWS service with the identity, logging and compliance plumbing already attached, which is the usual hyperscaler trade: less flexibility, far less integration work, and a security review that is mostly already done. Its natural pairing is Bedrock, which we list, for teams keeping the whole agent stack inside AWS.
