OBS Studio developed with cross-platform support. Official releases are currently available for Windows, Mac and Ubuntu Linux. There are also some unofficial releases for Arch Linux, OpenSUSE and Gentoo. And of course, since source code is open, you can build it for your OS.

It also has powerful API, enabling plugin development to provide further customization and functionality specific to your needs.
