Opera Unite

Press Page Down and Page Up to switch slides


Opera Unite is a technology that makes your browser into a personal web server. This changes everything: from being an onlooker, you become a participant on the Web! With Opera Unite, you are both client and server, both visitor and host. You receive web content, and you also provide it. And you remain in control: your data stays on your computer, and you decide with whom you will share it.

To make it easy to manage your web server and to give it useful functionality, Opera Unite includes numerous applications. By default, the following applications are included:

File Sharing
Makes your files accessible from other computers
A place to leave notes
Media Player
Streams your music
Enables communication with your My Opera friends
Photo Sharing
Presents your photos as a gallery or slideshow
Web Server
Displays your webpages

Additional applications are available from http://unite.opera.com/.

To use Opera Unite, you need an Opera account. The username and password for your Opera account is also valid on the My Opera community website, the developer site Dev.Opera, and with Opera Link.

Note: Since Opera Unite applications are available through Opera, and the data is stored only on your computer, your applications will be unavailable once you have exited Opera or shut down your computer.

Enabling Opera Unite

To enable Opera Unite, take the following steps:

  1. Select Tools > Opera Unite Server > Enable Opera Unite from the menu, or click on the Opera Unite icon, located on the bottom left of the browser on the status bar, and select "Enable Opera Unite".
  2. A wizard helps you to sign up for an Opera account. If you already have an Opera account, click on the button marked "I already have an account".
  3. During signup, choose a "computer name", so that the web server attached to this instance of the browser will have a unique name, and will be accessible to others. The web server address has the form http://computername.username.operaunite.com/, where "username" is the username attached to your Opera account, and "computername" is the computer name you have chosen.
  4. The "Advanced Settings" button regulates the degree to which your applications are visible to others.

You can at any time disable Opera Unite, stopping all applications, by taking one of the following steps:

Managing applications

Applications are managed from the Unite panel. There are numerous ways to open the panel, including the following two:

To start an application, take the following steps:

  1. Select an application from the Unite panel, and click on "Start". Alternatively, double click the application, or right click and choose "Start".
  2. The application explains what you have to do. For content-sharing applications, choose a folder on your computer where you will place the shared content. The "Advanced Settings" drop-down regulates the degree to which this application is visible to others.
  3. The presentation of an application depends on your relation to it. By default, you will be presented with the owner's view, with visible passwords that can be changed by clicking a form element. To see the application as a visitor would see it, click on "Preview as visitor".
  4. By default, content-sharing applications are password protected. To make an application open and accessible to everyone, select the radio button marked "Public".
  5. The activity level of running applications is indicated in the Unite panel.

To stop a running application, highlight the application in the Unite panel and click "Stop", or right-click the application and select "Stop". Note that disabling Opera Unite, exiting Opera, or shutting down your computer will stop all applications.

Visiting applications

So that visitors can see your application, you have to give them its web address, and possibly a password.

All running applications are assigned a unique web address. In the owner's view, the web address is written on the upper right side of the page (under "Sharing"), with the password just below. You do not need Opera to visit an application; any standards-compliant browser will do.
