The ability to record and share what's going on on your screen is invaluable depending on what you need it for. Tutorials and how-to videos explaining certain functions of an operating system or an app is an easy to see example, but other uses, such as repeating steps to showcase a bug or glitch so developers can get to the root of a problem and resolve it, are also important.
Because of how easy it is to see the benefits of screen recording software, it can be daunting to choose just what kind you want. That's where Screencast-O-Matic can come in. Screencast-O-Matic is a freemium screen recorder that allows you to record up to 15 minute-long recordings for free, with support for adding multiple audio tracks. It also does not require you to download a client to use.
If you don't mind using a traditional dedicated client, there are alternatives available on Windows, macOS, Linux, as well as Android and iOS. Several of these alternatives also feature some of Screencast-O-Matic's more convenient quality-of-life and time saving features such as support for uploading directly to YouTube or Dropbox within the app alongside more intricate features that Screencast-O-Matic doesn't have like support for recording audio activity from your desktop as well.
Screen recording has come a long way. With plenty of options available to record your screen, in addition to the alternatives available above that tout convenient features, you'll find great completely free and open source alternatives to Screencast-O-Matic that can be used with added peace of mind.
