A capybara driver that uses WebKit via QtWebKit.

Dependent on Qt

capybara-webkit depends on a WebKit implementation from Qt, a cross-platform development toolkit. You'll need to download the Qt libraries to build and install the gem.

OS X Lion 10.7:

Install Qt via homebrew(can take more than an hour) using:

brew install qt --build-from-source

OS X < 10.7:

Download the non-debug Cocoa package.


apt-get install libqt4-dev


yum install qt-webkit-devel

Gentoo Linux:

emerge x11-libs/qt-webkit

Other Linux distributions:

Download this package.


If you're like us, you'll be using capybara-webkit on CI.

On Linux platforms, capybara-webkit requires an X server to run, although it doesn't create any visible windows. Xvfb works fine for this. You can setup Xvfb yourself and set a DISPLAY variable, or try out the headless gem.


Add the capybara-webkit gem to your Gemfile:

gem "capybara-webkit"

Set your Capybara Javascript driver to webkit:

Capybara.javascript_driver = :webkit

Tag scenarios with @javascript to run them using a headless WebKit browser.
