Open Broadcaster Software download

NOTE: Please visit our website for downloads.

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.

This project is free and licensed under the GNU General Public License v2.

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 The screenshot is also outdated.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

Powerful video mixing and streaming software. Native C / C++, no bloat, just easy and fast. You can definitely run into problems if you don't know what you're doing though!

Absolutely horrendous, will not work at all with full screen games, will not stream properly for windowed games, does not link up with your stream comments, and is not user friendly whatsoever. Absolutely terrible piece of crap I've wasted far too many hours trying to get it to work. I guess they updated it to be more of a pain than it was, because none of those videos showing you how to get it going work at all.
