There is no website that says who is winning at the moment, however, there are other ways to research the development of players within the game, for example:
https://tibiafrags.com -> there is information about character frags and death history, some data from all Tibia worlds and many other useful resources.
www.twitch.tv -> Twitch TV is a video streaming platform focusing on electronic game broadcasts, including sports championships broadcast live or on demand. The platform offers channel titles about titles like Epic Games' Fortnite and of course Tibia.
www.tibia.com/forum -> Place where you can select the server and search for death comments, freedon and transfers to our server.
through a group of platforms you can update yourself about the war.
