Browser Workloads You Can Move From Hyperbrowser
Real Browser Checks for User Flows
Browser Cloud runs user-facing flows in real Chrome to confirm pages render, scripts run, and buttons work, which a server response code alone cannot prove.
Structured Data From Rendered Pages
Browser Cloud executes the JavaScript that single-page apps need, so agents read listings, job feeds, and other client-rendered data from the final DOM.
Real Chrome Sessions for AI Agents
Browser Cloud gives Claude, Cursor, Gemini, OpenAI Computer Use, and custom agents a real cloud Chrome session to read and act on the live web.
Multi-Step Flows With Session State
Browser Cloud carries login cookies and CSRF tokens from screen to screen, so agents can complete onboarding portals, partner dashboards, and back-office flows.
Price and Inventory Monitoring
Pricing teams track prices, variants, and stock levels across storefronts with Browser Cloud, using parallel sessions to monitor many SKUs on a schedule.
Web Data for Model Training
Browser Cloud's fleet of real browsers captures the hydrated, rendered state of web pages at scale for model training and evaluation datasets, not raw markup.
Migrate Hyperbrowser Sessions to Browser Cloud
Migrate your Node.js Playwright, Puppeteer, or Selenium code from Hyperbrowser by swapping the session client. The Connect to Session guide covers each framework.
Replace the Hyperbrowser SDK
Remove @hyperbrowser/sdk and add @testmuai/browser-cloud to your Node.js project.
npm install @testmuai/browser-cloud
Set TestMu AI Credentials
Replace HYPERBROWSER_API_KEY with the LT_USERNAME and LT_ACCESS_KEY values from your TestMu AI dashboard.
Connect the SDK Adapters
Connect through client.playwright, client.puppeteer, or client.selenium instead of a Hyperbrowser endpoint.
Hand the Rewrite to Claude Code or Cursor
Add the Browser Cloud agent skill, then ask your coding assistant to replace the Hyperbrowser client calls with Browser Cloud SDK calls.
