Open Broadcaster Software is free and open source software for the purposes of streaming live media content to the internet or to video files. Originally I made Open Broadcaster Software for myself because I thought "why should I pay a subscription for software I could probably write?" And so, I did and Open Broadcaster Software evolved into somewhat of a monster of a project. That's pretty much the Open Broadcaster Software story.

I hope people can make use of Open Broadcaster or learn something from it. I know I'm having a ton of fun writing Open Broadcaster and am learning much in the process. Overall it's been an excellent experience.

User Reviews

  • If you want to download Video, Streams, Vods, Recordings on Mac/Windows,I highly recommend Allavsoft

  • Make sure to check out the latest version of OBS and OBS-Studio. Sourceforge has only very old sources. The screenshot is also outdated.

  • The learning curve is a bit steep but a short 5-minute tutorial on YouTube got me ready with everything I needed to know. I used to use BB Flashback Express before I found OBS, and OBS is definitely more full-featured, albeit slightly less user-friendly.

  • It's a great screen recorder, it includes everything i need. With the right settings you have a better programm than Fraps or DxTory. The files are very small and fast to render (XMedia Recode) and upload. When you want a free programm you need THIS. Knollee
