Portable Apps

Your computer, without the computer
We use many apps on our computer, which we are familiar with, on a day to day basis. When travelling or when we do not have access to our own computer, it becomes inconvenient to use another app on someone else’s machine. E.g. if we are accustomed to using Google Chrome as our browser and we do not have access to the same elsewhere, it could be disconcerting and painful to use another browser. That is where Portable Apps come in.
The PortableApps.com Platform™ is a full-featured portable software system that ties all your portable apps together and lets you build your own custom portable app suite for use in your synced cloud folder, on your local PC, or on a portable USB drive. And it is kept separate from your local apps. The PortableApps.com Platform is 100% Free. Free to use. Free to share. And fully open source.
What it does is that it creates an entire suite of commonly used apps, in compressed form which you can save to your pen-drive, USB drive or on the cloud. Whenever you need to use these apps, you may use them directly off the USB drive or the Cloud without having the need to install them on the local machine.
