Addon that shows enemy class?

[Vinzora-draenor]

For example to show class by unit frame in top left corner?

[Elvenbane-kazzak]

Any Unit Frame addon will be able to do that.

ElvUI being one of the most popular https://www.tukui.org/

The ones I saw completely change the UI. I’m looking for one that keeps the Blizzard frames but just adds a class icon or color.

Take a look at Easy Frames. They’re very similar to the standard frames but with class colors and a nice fat health bar that’s easy to see for old farts like me.

I found one called Simple Class Frames. All it does is replace the portrait of target with a class icon. Pretty much what I was looking for.
