What is SUSE Studio Express?
Studio Express is a simple and fast appliance (custom operating system) builder, which provides an easy to use, web-based user interface and will run in your browser without other needed software. One great feature is the SUSE Studio Express Testdrive. You can boot, configure and test your newly build operating system in a browser window without downloading anything.
SUSE Gallery is the place where you can find an existing appliance that you can download and use immediately. It is tightly integrated with SUSE Studio Express, so you can easily start to customize the appliances if you want to do so.
