What is Jetpack?

Back in the day, there were great features available to WordPress.com users that were not available on self-hosted WordPress installs. Jetpack is a plugin that connects to WordPress.com and enables awesome features, powered by our cloud infrastructure.

What features does it have?

  • Beautiful Math: Mark up your posts with the LaTeX markup language, perfect for complex mathematical equations and other über-geekery.
  • Carousel: Transform your standard image galleries into an immersive full-screen experience.
  • Comments: Give your readers the ability to comment using their WordPress.com, Twitter, or Facebook accounts.
  • Contact Form: Insert a contact form anywhere on your site.

  • Enhanced Distribution: Share your public posts and comments to search engines and other services in real-time.
  • Extra Sidebar Widgets: Add images, Twitter streams, and your site’s RSS links to your sidebar.
  • Featured Content: The Featured Content module allows you to display specific posts in a highlighted area on your site’s home page, letting your draw attention to your most important content.

  • Infinite Scroll: Learn how to add infinite scroll support to your theme.
  • JSON API: Allow applications to securely access your content through the cloud.
  • Likes: Likes are a way for people to show their appreciation for content you have written. It’s also a way for you to show the world how popular your content has become.

  • Post by Email: Post by Email is a way of publishing posts on your blog by email. Any email client can be used to send the email, allowing you to publish quickly and easily from devices such as cell phones.
  • Publicize: Publicize makes it easy to share your site’s posts on several social media networks automatically when you publish a new post.
  • Social Links: this module is a canonical source, based on Publicize, that themes can use to let users specify where social icons should link to.
  • Sharing: Share your content on Facebook, Twitter, and more with a few simple clicks.
  • Shortcode Embeds: Embed content from YouTube, Vimeo, SlideShare, and more into your site, no coding necessary.
  • WP.me Shortlinks: Enable WP.me-powered shortlinks for all of your Posts and Pages for easier sharing.
  • Spelling and Grammar: Improve your spelling, style, and grammar with the After the Deadline proofreading service.

  • Tiled Galleries: Display your image galleries in three new styles: a rectangular mosaic, a square mosaic, and a circular grid.
  • Toolbar Notifications – Get notified of activity on your site, right from the toolbar.

Some of these features use the powerful WordPress.com cloud, others are popular features provided for the convenience of not having to install and manage several separate plugin installations.

What is required to install Jetpack?

Any WordPress site running the latest version of WordPress (or the version before) can install Jetpack just like any other plugin. Some hosting providers will auto-install Jetpack with WordPress, saving you the trouble.

If you use WordPress.com, you don’t need Jetpack, as its features are already bundled into WordPress.com.

After you install Jetpack, connect it to WordPress.com with a WordPress.com account. If you don’t have one already you can create one very easily during the connection process.

If you’d like to use Jetpack without connecting it to a WordPress.com account, you can enable the development mode.

Who should install Jetpack?

Anyone who is hosting their own WordPress (anywhere except WordPress.com), and wants to take advantage of the awesome features that Jetpack provides.

Is Jetpack Free?

Jetpack itself is, and always will be free. Some individual features that Jetpack provides will be free, but others in the future may require payment. Installing Jetpack is free and requires no payment information.

I already use a plugin that is now part of Jetpack (such as WordPress.com Stats). What do I do now?

As we upgrade each of our individual plugins to be a part of Jetpack, we’ll prompt you to switch over to the new, Jetpack-powered version. Don’t worry about upgrading, we’ll automatically take care of carefully switching over all of your settings and options so that it’s the smoothest experience possible. Once you’ve upgraded to Jetpack, you can remove the older versions of those plugins.

Is this related to Mozilla’s Jetpack project?

Mozilla Jetpack is a wonderful, but entirely unrelated, open source project run by Mozilla Labs, which, if you know HTML/CSS/JavaScript, makes it easier than ever to improve Firefox. We checked with them beforehand and mutually agreed our use of the Jetpack name would be fine.
