If you are looking for a way to connect to your favorite instant messaging network without having to install any kind of software on your computer you have certainly come to the right place.

We all know that instant messaging represents the most popular form of real-time communication between two or more people based on typed text. This type of communication is generally possible through the use of appropriate client software that needs to be installed on computers connected over a network such as the Internet.
However, the necessity to boost cross-platform communication has recently generated a major need for instant messaging applications that could be used by anybody, independently of the operating system they were adopting and - more importantly - without the need to download and install anything on the computer.
In this mini-guide I have reviewed for you the most popular services that allow you to access your favorite instant messaging networks from any browser and any operating system, without the need to install software. At the end of the mini-guide you will also find a handy set of tables allowing you to easily compare all the different tools that have been featured here.
As always, you are more than welcome to suggest and revise our data through the comment section available at the bottom of the article.
