Yeah, there is absolutely nothing special about guitar or missing on bass, besides usefulness, that would makes them not work on bass. Les Claypol has one and uses it, but since you can bend strings yourself on bass, where as on guitar it’s harder because of chords, they aren’t popular.
Here’s the only company I know that makes one, and probably all you need.

I will add that I have a de-turner on my four string and love it, so check out those as well.
