Agent Browser With Real Chrome Sessions

An agent browser is a real web browser built for AI agents to drive, instead of a person clicking through it. The AI doing the driving is a browser agent, such as Kane CLI. TestMu AI Browser Cloud is that browser layer, with real, isolated Chrome sessions on demand for any AI agent.

Yes. At TestMu AI, both names describe the same product, Browser Cloud, which is cloud infrastructure for your AI agents. Browser Cloud gives each agent real, isolated Chrome sessions on demand, a built-in localhost tunnel, session transparency, and persistent logins.

An agentic browser is a browser that an AI agent operates on its own, reading the page, deciding the next step, and acting. Browser Cloud is not one itself but the infrastructure underneath one, providing real Chrome sessions that agentic products and custom agents drive through the Session SDK, an agent skill, or an MCP server.

Claude, Cursor, Gemini, OpenAI Computer Use, and custom agents all work with Browser Cloud. AI coding assistants such as Claude Code and Cursor install the agent browser skill to learn the Session SDK and write the integration. Other agents call browser tools through the agent browser MCP server or the agent browser CLI, testmu-browser-agent.

Operator is OpenAI's own app, so it does not run on Browser Cloud. Agents you build with OpenAI Computer Use or Anthropic's Claude computer use can drive Browser Cloud sessions through SDK calls, so the model's on-screen reasoning acts on real cloud Chrome. These are connection paths, not partnerships.

Through the TestMu AI Tunnel, which ships built into Browser Cloud. Start the tunnel during session setup, and a cloud session can open localhost:3000, a staging build, an internal dashboard, or a service inside your VPN without exposing it to the public internet. Public URLs do not need the tunnel.

Use the video, console logs, network request and response logs, and step-by-step command replay that Browser Cloud records on every session. Replay the commands to find where the run diverged, check the logs for errors, and watch the video to see the page the agent saw. Together they cover the browser side of AI agent observability.

AI agent observability means seeing what an agent did and why. Tracing tools record prompts, tool calls, and model outputs, and Browser Cloud covers the browser side, recording video, console logs, network logs, and command replay for every session, so you can see the page the agent acted on.

Not reliably, and no service can promise it. Point your Puppeteer scripts at a Browser Cloud session and turn on Stealth Mode, a best-effort mix of fingerprint masking, CAPTCHA solving, and ad blocking that helps reduce blocks on legitimate automation. Stealth Mode does not make sessions undetectable, and results vary by site, so test against your own targets.

Yes. Connect your existing Playwright, Puppeteer, or Selenium code to real Chrome sessions in Browser Cloud with little change, and run AI agent browser automation across many sessions in parallel. For test suites across Firefox, Safari, and real devices, use TestMu AI Automation Cloud and the real device cloud with 50,000+ Android and iOS devices.

A plain HTTP scraper sees an almost empty HTML shell on single-page apps, and a self-run headless fleet is yours to scale and debug. Browser Cloud renders pages in real Chrome, runs sessions in parallel, records every session, and keeps logins across runs. Respect each site's terms and the law. See AI browser automation for the natural language view.

Browser Cloud limits the risk in three ways. Each session runs in its own isolated cloud environment, the built-in tunnel reaches private apps without exposing them to the internet, and access keys stay in environment variables or CI secrets. The platform is SOC 2 Type II and ISO 27001 certified, and Enterprise adds SSO and IP whitelisting.

Kane CLI is a separate TestMu AI product, a deterministic browser agent that runs natural language objectives from your terminal, drives real Chrome over the Chrome DevTools Protocol, and returns exit codes 0 to 3 for CI. Kane CLI is free to install, runs on local Chrome, and can connect to a remote browser endpoint. Each run uses KaneAI credits from your TestMu AI account, and you can start free with 10,000 credits, valid for 30 days. See Kane CLI or the Vercel agent-browser comparison.
