Frequently Asked Questions
What is cross-browser testing?
Cross-browser testing verifies that a website or web application works correctly across different browsers (Chrome, Safari, Firefox, Edge, Internet Explorer), browser versions, operating systems and screen sizes. It catches rendering inconsistencies, JavaScript compatibility issues and CSS bugs before users encounter them. TestingBot runs your tests on 6100+ real browser and OS combinations in parallel.
How do I test a website on multiple browsers?
Use a cross-browser testing platform like TestingBot. Sign up, point your Selenium, Playwright, Cypress or Puppeteer test scripts at the TestingBot grid by changing the WebDriver URL, and your tests run in parallel across thousands of real browsers and devices. You can also start live, interactive sessions on any browser without writing code.
Which test automation frameworks does TestingBot support?
TestingBot natively supports Selenium, Appium, Playwright, Cypress, Puppeteer, Espresso, XCUITest and Maestro. SDKs are available for Java, JavaScript, TypeScript, Python, Ruby, C#, PHP and Go. AI assistants like Claude Code and Cursor can also access the TestingBot REST API via a Model Context Protocol (MCP) server to inspect test runs and debug failures from your editor.
Does TestingBot support real iOS and Android devices?
Yes. TestingBot operates a cloud of physical iOS and Android devices, including iPhones (from iPhone 6s to iPhone 17 Pro), iPads, Samsung Galaxy phones, Pixel devices and tablets. You can run automated Appium, Espresso, XCUITest or Maestro tests on real hardware, or take manual control via the live testing interface.
How is TestingBot different from BrowserStack, Sauce Labs and LambdaTest?
TestingBot is more affordable than BrowserStack and Sauce Labs (typically 30 to 40 percent cheaper), includes real device testing in every paid plan, hosts data in the European Union for GDPR compliance, and ships features faster — Apple Silicon support arrived more than ten months before Sauce Labs. See the dedicated comparisons: BrowserStack alternative, Sauce Labs alternative, LambdaTest alternative.
Does TestingBot support AI-driven testing?
Yes. TestingBot offers codeless AI testing — describe in plain language what you want to test, and an AI agent creates and runs the test on the browsers you choose, reporting back any failures. TestingBot also exposes its REST API via a Model Context Protocol (MCP) server so AI assistants like Claude Code and Cursor can inspect test runs, fetch logs and debug failures from your editor. See the full AI testing overview for integrations with Magnitude, Stagehand and Notte.
Where is TestingBot data hosted?
TestingBot is built and hosted in the European Union. All test data, video recordings and logs are stored on EU-based infrastructure, making TestingBot a strong choice for GDPR-compliant testing programs and for teams with European data-residency requirements.
Is there a free trial?
Yes. TestingBot offers a free plan and a free trial of paid features. No credit card is required to start. During the trial you can run automated tests, live manual sessions, screenshot tests and visual comparisons on browsers and real devices.
