We would like to open a screen recorder online and start to record web pages and desktop screens without downloading or installing any software. Unfortunately, that's not the way an online screen recorder works.

Desktop or online screen recorder? Well, it depends. Desktop screen recorders are usually more stable for recording and generally with more functionalities while online screen recorders are smaller in size and enable you to record screen from the web (thus online screen recorders will not be available if there's something wrong with your internet connection).
