Important message: From Opera 12, Opera Unite has been removed by default for new users and will eventually be phased out. We encourage all developers to move their solutions to the extension platform.
Opera Unite is a technology that makes your browser into a personal web server. 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/.
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:
- Go to Add-ons: Opera Unite.
- 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".
- 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.
- 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:
- Select from the menu, and choose "Disable Opera Unite".
- Click on the Opera Unite icon on the status bar, select "Configure" and choose "Disable Opera Unite".
Applications are managed from the Unite panel. There are numerous ways to open the panel, including the following two:
- Select from the menu.
- Click on the Opera Unite icon on the status bar, and select .
To start an application, take the following steps:
- Select an application from the Unite panel, and click on "Start". Alternatively, double click the application, or right click and choose "Start".
- 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.
- 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".
- By default, content-sharing applications are password protected. To make an application open and accessible to everyone, select the radio button marked "Public".
- 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.
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.
