Ranch is mayonnaise-based, but is savory, with seasonings and plenty of umami. There’s a lot of variation, and IMO the best version is Uncle Dan’s (Amazon).
It’s a cream dressing, so plenty heavy. Often used for dipping stuff. With Uncle Dan’s (which comes as a powder), you mix it with buttermilk and mayo for a dressing; or you mix it with Greek yoghurt (or sour cream) and mayo for a dip.
It’s basically the American version of salad cream.
That’s an unfair comparison.
