At the end of Zootopia we observe that Judy and Nick have become really close to each other but are they maintaining a best friend type relationship or a romantic relationship? I think that it is only a friend relation, but is there any evidence of this?
During the movie they become good friends. As to that ending scene and the future after that, it seems it's intentionally ambiguous. The directors (Mainly Rich Moore) seem to be having great fun playing with this fact on Twitter.

@_rich_moore Already seen the movie and I have to say it was awesome; but I have a question which is the relationship between Judy and Nick?
