Not even close, Proton is a translation layer from Win32 API to whatever works similar for Linux, SDL just gives a higher level API of lower level stuff, like instead of using Xorg/Wayland directly, you get a nicer cross platform API that does the job well
So kind of like proton, except for multiple platforms and in the source code instead?
