PhantomJS ([www.phantomjs.org](http://phantomjs.org)) is a headless WebKit scriptable with JavaScript. It is used by hundreds of [developers](http://phantomjs.org/buzz.html) and dozens of [organizations](http://phantomjs.org/users.html) for web-related development workflow.
The latest [stable release](http://phantomjs.org/release-1.9.html) is version 1.9 (codenamed <ahref="http://phantomjs.org/release-names.html">"Sakura"</a>). Follow the official Twitter stream [@PhantomJS](http://twitter.com/PhantomJS) to get the frequent development updates.
The next major version, PhantomJS 2, is a significant upgrade. It is still in [heavy development](https://github.com/ariya/phantomjs/wiki/PhantomJS-2). There is **no timeline** for the release yet, please monitor the [mailing-list](https://groups.google.com/forum/#!forum/phantomjs) for the progress.

- **Headless web testing**. Lightning-fast testing without the browser is now possible! Various [test frameworks](http://phantomjs.org/headless-testing.html) such as Jasmine, Capybara, QUnit, Mocha, WebDriver, YUI Test, BusterJS, FuncUnit, Robot Framework, and many others are supported.
- **Page automation**. [Access and manipulate](http://phantomjs.org/page-automation.html) web pages with the standard DOM API, or with usual libraries like jQuery.
- **Screen capture**. Programmatically [capture web contents](http://phantomjs.org/screen-capture.html), including CSS, SVG and Canvas. Build server-side web graphics apps, from a screenshot service to a vector chart rasterizer.
- **Network monitoring**. Automate performance analysis, track [page loading](http://phantomjs.org/network-monitoring.html) and export as standard HAR format.
