What is the best Browserbase alternative for AI agents?

Pick by the job your agent does. Browser Cloud by TestMu AI fits agents that work on private or logged-in apps and need every session recorded. Steel and Browserless fit teams that want to run the browsers on their own servers, Kernel fits agents that sit idle between steps, and Bright Data fits high-volume scraping behind proxies.

Is there an open-source Browserbase alternative?

Yes. Steel's browser API is open source under the Apache 2.0 license, and Kernel publishes its browser images under Apache 2.0. The Browser Use agent library is MIT-licensed. Browserless is source-available under SSPL, so using it inside a closed-source product requires its commercial license. Browserbase's own Stagehand SDK is MIT-licensed, but Browserbase does not offer on-prem deployment.

How does Browser Cloud compare to Browserbase?

Both run cloud browsers for AI agents, with Playwright, Puppeteer, and Selenium support, session recordings, persistent state, and CAPTCHA solving. Browser Cloud adds a built-in tunnel to localhost and staging and lists SOC 2 Type II, ISO 27001, PCI DSS, HIPAA, GDPR, and CCPA. Browserbase adds built-in proxies in 200+ countries and Stagehand, an open-source SDK.

Is Kane CLI an alternative to Stagehand?

Kane CLI and Stagehand do different jobs. Stagehand is Browserbase's open-source SDK that adds AI steps such as act, extract, and observe to the code you write. Kane CLI is a TestMu AI browser agent that runs a natural language objective in real Chrome and returns a pass or fail with exit codes 0 to 3 for CI.

Can Browser Cloud reach localhost or private environments?

Yes. The built-in TestMu AI Tunnel lets Browser Cloud sessions reach localhost:3000, staging builds, internal dashboards, and services inside a VPN without exposing them to the public internet. Browserbase does not document a built-in localhost tunnel, and its pricing FAQ lists VPC connectivity without naming a plan.

How do I move Playwright, Puppeteer, or Selenium scripts from Browserbase?

Point your existing Node.js code at a Browser Cloud session instead of a Browserbase session. Browser Cloud drives sessions with Playwright, Puppeteer, or Selenium, so scripts, page objects, and helpers carry over with minimal change. Coding assistants such as Cursor and Claude can add the Browser Cloud agent skill and write the integration for you.

Should we build our own browser fleet instead of using Browser Cloud?

Building your own fleet makes sense when browser infrastructure is core to your product. Otherwise, a self-run Playwright or Puppeteer fleet means provisioning servers, adding proxy and CAPTCHA services, building logging and replay, and patching browsers. Browser Cloud runs real Chrome sessions in parallel as managed infrastructure, so your team spends its time on agents.

Does Browser Cloud handle bot detection and CAPTCHAs?

Browser Cloud Stealth Mode combines fingerprint masking, CAPTCHA solving, and ad blocking to reduce blocks on legitimate automation. Stealth Mode is best-effort and does not make sessions undetectable. Results vary by site. Browserbase offers CAPTCHA solving and proxies on its paid plans and Verified browsers on its Scale plan.

Which operating system is optimized for web apps?

ChromeOS, which Google builds around the Chrome browser and where, in Google's words, web apps are a core feature throughout the operating system. Browser Cloud runs on the same browser: every session is real Chrome running in the cloud, so web apps render and run JavaScript the way they do on a user's machine. Your agent connects with Playwright, Puppeteer, or Selenium from Windows, macOS, or Linux, so the operating system on your laptop or CI runner does not limit what it can automate.

What does "No installed apps found" mean on Android?

It is usually the Android prompt "No installed apps work with this USB accessory," which appears when you connect an accessory, such as an Android Auto car unit, and no app on the phone handles it; installing or updating that app, then reconnecting, clears it. Browser Cloud has no app install step that can fail this way: each session is a real Chrome browser in the cloud, and the machine running your agent needs only the @testmuai/browser-cloud package and your TestMu AI credentials. For native Android apps, TestMu AI's real device cloud tests installs on 10,000+ real devices.

AI Agent Use Cases on Browser Cloud

Real-Time Structured Data Extraction

Browser Cloud runs real Chrome, so single-page apps hydrate and agents read the fully rendered DOM for pricing checks, inventory monitoring, and job feeds.

Multi-Step Workflow Automation

A Browser Cloud session keeps cookies, CSRF tokens, and client-side state across steps, so multi-step login and form flows run from start to finish.

Real-Time Web Access for Agents

Browser Cloud points your agent at the live web, so it reasons over current prices, availability, status pages, and listings instead of a stale snapshot.

Locally Hosted App Automation at Scale

The built-in tunnel lets Browser Cloud sessions reach localhost, staging, internal admin tools, and VPN-only apps at scale without exposing them publicly.

QA Automation Against Real Browsers

Browser Cloud checks that user-facing flows render, run JavaScript, and work in real Chrome, which an uptime ping or HTTP status check cannot show.

Foundation Model Training Data

Browser Cloud captures web pages as real Chrome renders them, so training and evaluation datasets reflect what users and agents actually see.
