Browser Use vs Amazon Nova Act (2026): which should you pick?

Pick Browser Use if

• Fits if you are a developer who wants browser agents with a free harness
• Works for someone who prefers pay as you go to a subscription

Look elsewhere if

• Not for you if you want a no-code app, as it is built around an API key and docs
• Watch out: costs follow use at $0.02 a browser hour and $5 a GB on home-IP proxies
• Tight if you scale: concurrency starts at 10 and is 50 after $100 paid
• Watch out: the default model rate is $0.12 per million input tokens, and other models cost more

Pick Amazon Nova Act if

• Fits if you already build on AWS and write Python
• Works for developers who want browser tasks that can hand off to a human

Look elsewhere if

• Not for you if you want no-code, as it needs code and an AWS account
• Watch out: the documentation lists a single supported Region, US East (N. Virginia)
• Pricey if you run many agents: each parallel agent is billed on its own at $4.75 an hour
• Skip it if you want a free try, as none is listed

Browser Use

• Costs follow use: $0.02 per browser hour, $5/GB on home-IP proxies and $0.20/GB direct.
• The default agent model rate is $0.12 per million input tokens and $0.60 output; other models cost more.
• Concurrency unlocks by total paid: 10 at the start, 50 after $100, 250 after $1,000.
• Aimed at developers: the page lists an API key and docs, not a no-code app.

Amazon Nova Act

• The documentation lists a single supported AWS Region, US East (N. Virginia).
• Billing is by agent hour, so cost depends on how long workflows run; each parallel agent is billed on its own.
• It needs an AWS account and code; there is no no-code builder on the pages read.

Browser Use

Web agents

Send a task and get JSON back. The pricing page lists a median task at $0.006 on the default model.

Stealth cloud browsers

Cloud browsers with CAPTCHA solving included and home-IP proxies, billed per browser hour plus traffic.

Browser Harness

A free, MIT-licensed tool that gives coding agents such as Claude Code and Codex control of your own Chrome.

Choice of models

Agents run on the vendor's BU models or models from OpenAI, Anthropic and others; bring your own key at provider cost plus 0.2x.

Enterprise deployment

US or EU cloud regions, on-prem browsers and agents through sales, and SOC 2 Type II with HIPAA and zero data retention available.

Amazon Nova Act

Natural language plus Python

Each act() call passes a plain-language task to the model inside a session, and the surrounding script is ordinary Python.

Browser workflow automation

Listed uses include data entry into web forms, extracting fields from sites and dashboards, and running QA test cases in the browser.

Human-in-the-loop

An agent can escalate to a human supervisor when appropriate, and the waiting time is not billed.

Tools and APIs

Agents can call APIs and remote MCP tools, or use other agent frameworks, alongside the browser.

AWS deployment and monitoring

Native integration with Amazon Bedrock AgentCore for deployment, CloudWatch for monitoring and IAM for permissions.
