Surprised no one has mentioned OBS. I don’t use it for streaming, but afaik it’s one of the more popular options for that. So it’s really cool that not only is it available for linux, but it’s open source and works great. I’m sure every linux user has had audio, general hardware, or GPU acceleration issues at some point, but OBS is seamless in my experience. Pretty cool to see a piece of software live at the crossroads of all that and get it right.

Mint is Debian based. Mullvad supports debian.
