OBS is licensed under GPLv2 with code available on GitHub. It's available on Windows, OSX and Linux.

Open Broadcaster lets you add different streaming profiles, each with its own settings. Each profile can have its keyboard shortcut to start or stop recording, custom resolution, frames per second or even the audio codec of choice.

OBS has over 20 plugins to choose from, including one's that allow adding video files and any other media supported by VLC as a source, integrating Twich chat and switching scene depending on what window is in focus.

Quick Sync is hardware video encoding and decoding technology that's comparable in speed, compression ratio and quality to x264. Since Quick Sync is a dedicated hardware core on the processor die, it allows for faster and more power efficient video processing.

Open Broadcaster uses relatively fewer resources than competitors, especially when streaming using Game Mode and by limiting the number of frames per second to 60 or lower.

There are multiple capture types that can be used to stream. By clicking in "Sources Window", you can add the type that you need. Windows Capture_, for example, as the name suggests, captures the windows. _Monitor Capture is similar but captures the window regardless of where it was, this way you can for example capture the whole monitor or a sub-region of the screen. But the most important capture type by far is _Game capture_, which allows users to record full screen captures of games.

OBS can stream to any RTMP-enabled service, including Twitch, YouTube, DailyMotion, and Hitbox.

Version 22.0.2 for Windows has a new simpler to use interface with a multitude of easily accessible settings.

OBS allows to look at scenes before streaming them in Studio Mode.

Open Broadcaster has a clean and simple interface that is easy to understand even for people who have never used a streaming application before. It has a "Start Streaming" button on the bottom, which, when clicked lets you stream from your chosen source.
