help Watir FAQ

Which browsers can Watir automate?

Watir drives browsers through Selenium WebDriver and is commonly used with Chrome, Firefox, Edge, and Safari. The exact browser requires a compatible driver and support from the operating system.

Do I need to write Ruby to use Watir?

Yes. Watir is a Ruby library, so tests are written in Ruby using calls such as locating a button by text or filling an input by name.

How is Watir different from Selenium?

Watir provides a Ruby-focused, readable API on top of Selenium WebDriver. Selenium supports several programming languages directly, while Watir is attractive to teams that want browser tests to feel idiomatic in Ruby.

Is Watir still useful when Playwright exists?

Watir remains practical for Ruby test suites and projects already built around Selenium's browser ecosystem. Playwright has first-party APIs for languages such as JavaScript, Python, Java, and .NET, but it does not offer an official Ruby client.
