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?

@_rich_moore I luv your film! But sometimes, friends could be couple, isn't it? Because..As nick&judy said at Ending, they love each other..

Mmmaybe...I guess we'll just have to wait and see what happens in the future 😉
There they are at the end of the movie couple, proves this conversation:
Nick: You know you love me.
Judy: Do I know that? Yes I do.
