Best Open-Source Screen Recorders

Edited by Ben Jacklin

March 25, 2021

There are many reasons why you might want to film your screen rather than taking a screenshot. Sometimes a still image isn't enough, and what you really want is a video showing the action on the screen. To achieve this, you will need specialized open-source screen recording software.

As with most software, screen recorders are not created equal. While there is free and open-source video capture software, they generally lack the flexibility and options of paid video editors.

Fortunately, we've helped you gather 12 open source software for different OS that you will no doubt fall in love with. These include OBS Studio, ShareX, CamStudio, VirtualDub, Simple Screen Recorder, Record My Desktop, Captura, UltraVNC, ScreenCam, Freeseer, Kazam, and XVidCap.

OBS Studio is open-source software that is not really intended for beginners. However, it is primarily aimed at those who want to stream on YouTube or Twitch. However, it can also be used to film what is happening on your Windows desktop. You can control the program via customizable hotkeys and use the built-in audio mixer to create excellent quality videos. OBS comes with live streaming capabilities that you won't find in native programs of major operating systems, in addition to screencast options. You can find help on their site, but to save you time, when using OBS Studio for the first time, click + in the Sources area and then select Display capture.

You will then see your desktop appear; you can specify the monitor if you have more than one. It will happily shoot games in full screen with game capture, which a lot of software refuses to do. OBS is powerful software, especially for a free product with so many features. It is a comprehensive tool for live streaming and recording.

How to Choose Open-Source Screen Recording Software?

Do you want to make video tutorials on your computer or on smartphones and tablets to share with other people to show them the use of some software or applications? If yes, you've seen the 12 best software that can perform this function.

In this section, we'll see how to choose an open-source screen recorder. But first, what is open-source screen recording software?

Open source screen recording software are often free video grabbing software that allows users to share and contribute. With a screen recording program, you can capture what happens on the display of your PC, laptop, or mobile device.

You can even record the taps you make on the screen with your fingers, cursor movements, or the moment you type a URL in the browser bar.

You can usually also record audio and, with some tools, make annotations on the screen.

Next, we're going to look at the things you should watch out for a while looking for open-source screen recording software.

Type of Software

The million-dollar question remains: which tool or app to use? You can find many on the market, and they all offer different features. There is desktop software that works with Windows PC or Mac.

Some are online services that can be accessed by virtually all devices and computers. Some are web extensions that are installed in a web browser. Meanwhile, some are programs that have to be downloaded and installed.

Software or Online?

In our list of screen recording programs, you've found online sites, browser-based software, and desktop applications with essential functions.

The fundamental difference between programs and online sites to record the screen is that with the former, you can work offline, while with the latter, you cannot.

For obvious reasons, if you want to use a site, your PC or laptop must be connected to the network. With desktop software, on the other hand, you can record your screen wherever you are and at any time, with or without the internet.

For example, if you're looking for a program to record gameplay, browser-based software is probably not the best option. If you want to create a tutorial instead, it might be the right solution.


Watermarks are unsolicited ads automatically inserted into videos made with freeware or software used under trial. However, the best open-source screen recording software should come with no watermark. There are many top free screen recording programs that do not leave any watermark on their videos. These include OBS Studio, ActivePresenter, QuickTime, Screencast O-Matic, TinyTake, Debut Video Capture, Apowersoft, AZ Screen Recorder, and more.

Software Features

Some software offers several recording modes, including full screen and selectable area. Some allow you to annotate video in real time and apply callouts, lines, text, and more without pausing.

Thanks to the intuitive and smartphone-specific functions, all you have to do is connect your PC and smartphone to the same WiFi network and start casting.

You can use some of this software for both screen capture and webcam video.

Others allow users to zoom, draw while adding overlays on their video files. These features are very convenient because they allow you to share your recordings on YouTube with no need to download any desktop program.

Some are capable of saving videos in just a couple of formats, while others can export the files for use on popular platforms like YouTube. Still, others, however, cannot record in HD.

That is why it is essential that you do some research and compare the various features of each program before downloading or installing one on your device.

Of course, your choice will directly depend on your goals. Maybe you don't need to record in HD, or you recently bought a video hosting plan and can do without exporting to a YouTube-compatible format. The best tool is simply the one that best suits your needs.

OS Compatibility

Perhaps the most crucial criterion, if you choose software that is not compatible with your computer or device's operating software, then it's all a waste of time and effort. While some are only compatible with Windows, some are compatible with Windows, Mac, and Linux. Others only work with the Android operating system or iOS. So, ensure you're getting software that works for your computer or device's OS.


This recording software should allow you to convert and save your recordings in all popular video formats, such as MP4, MOV, QT, and API. Other software will allow you to save to AVI, WMV, and the Flash formats, the FLV and SWF.

Saving and Sharing

The software must allow you to capture videos and let you save them into your computer's drive, phone memory, or an online cloud system. For easy upload on YouTube and other video hosting platforms, the software should allow you to share recordings.

Either way, the option you choose must meet these essential criteria:

  • It must be easy to use
  • It should be able to record both full screen and a specific area or window
  • It allows the user to make notes
  • It has a built-in audio and microphone system
  • It can record video from external sources
  • It is capable of exporting to various formats

Keep in mind that many of this software can record HD videos, but uploading them takes a long time; if your goal is to upload standard quality videos to the web, HD is not essential.

Meanwhile, we'd also advise you also to try out Movavi Screen Recorder. It's not open-source, but it's free and includes many features that will interest you.


Screen recording programs are much more intuitive today, and you can use them to do a variety of things with minimal effort. Many are available for free with the source code available publicly, allowing you to use, share, and contribute.

If you need to create tutorials or product descriptions, offer or request technical assistance or make video calls, whether you are looking for a more precise way to record your screen or just want to capture part of it, your PC or laptop screen recording program is not powerful enough. Then the listed software will help you out in sharing your gameplays, tutorials, or other video contents.
