Web apps have become increasingly popular over the last few years which lead Mozilla, the company behind Firefox to launch the Firefox OS. It was a mobile platform built solely on the promise of web apps. That didn’t take off for several reasons but Chrome OS, Google’s similar take for laptops, did. Web apps have a few advantages over native apps. You don’t have to “install” them, for one. They’re almost as fast as native apps these days but less resource hungry. They also have a few disadvantages, such as no real integration with your desktop. But on Linux, you can easily convert web apps into desktop apps.
Peppermint OS, a light-weight Linux distribution, makes heavy use of “Site Specific Browsers” or SSBs. Many web apps these days offer enough functionality to be native apps, but they lack the integration with the desktop. These SSBs provide that for web apps, allowing them to run outside of a browser. The developers of the lightweight Linux distro have even created an app called Ice. It allows users of Peppermint OS to convert web apps into native desktop apps. This works as long as you have either Chrome, Chromium, Firefox, and/or Vivaldi installed on your system.
The said Ubuntu distribution includes a number of SSBs by default, including some popular applications such as Google Drive and games such as Entanglement. No need to install Peppermint OS just to get Ice and a plethora of web apps though.
Peppermint OS is based on Ubuntu, and so most of its apps are readily available to install on any version or flavor of Ubuntu. Although you’ll probably not find Ice in the Ubuntu repositories, and thus neither the Software Center. But the program is available as a Debian package that you can download and install.
