What is OBS Studio?

OBS Studio is a complete rewrite of the original OBS from the ground up, formerly known as 'OBS Multiplatform', with the main goals of course being multiplatform support, a more thorough feature set, and a much more powerful API. While still in it's early stages, releases are currently available for Windows, Mac and Linux.

OBS Studio will eventually support many of the advanced requested features not present in the original OBS, such as multiple stream outputs and scene previewing, the latter of which is now available in the current release.

How much does it cost?

OBS is completely free! Not a dime! There are no subscriptions, no payments at all. OBS is available to everyone, with source code publicly available on github for anyone to help contribute.

While OBS will always remain free, you are welcome to donate to support our development efforts.

Plugins

OBS has an API allowing developers to create their own unique plugins, giving them and others complete control of their streaming experience. Some popular plugins include:
