It is used by hundreds of [developers](https://github.com/ariya/phantomjs/wiki/Buzz) and dozens of [organizations](https://github.com/ariya/phantomjs/wiki/Users) for web-related development workflow.

The latest [stable release](http://phantomjs.org/release-1.9.html) is version 1.9 (codenamed <a href="http://phantomjs.org/release-names.html">"Sakura"</a>). Follow the official Twitter stream [@PhantomJS](http://twitter.com/PhantomJS) to get the frequent development updates.

- **Page automation**. [Access and manipulate](https://github.com/ariya/phantomjs/wiki/Page-Automation) web pages with the standard DOM API, or with usual libraries like jQuery.
- **Screen capture**. Programmatically [capture web contents](https://github.com/ariya/phantomjs/wiki/Screen-Capture), 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](https://github.com/ariya/phantomjs/wiki/Network-Monitoring) and export as standard HAR format.

## Features

- **Multiplatform**, available on major operating systems: Windows, Mac OS X, Linux, other Unices.
- **Fast and native implementation** of web standards: DOM, CSS, JavaScript, Canvas, SVG. No emulation!
