[ REQUEST ] Looking for a tournament system.

Hello i own socomupdates.com. I keep updates for a game . But my buddy had an idea on having tournament but i dont want to do it the hard way by making an image with brackets and teams so on. I want to have something they can add a team and it will go on a bracket like this. https://cheque.ch.funpic.de/
