I have been working for this website for a quite long time. Now, it is ready to be published

The website updates charts once a day. The data is gathered from Relic's leaderboards automatically. The charts show only information from the players whose ranking is better than 201. Currently leaderboards of arranged teams are not tracked but it will be someday.
There are 1vs1, 2vs2, 3vs3, 4vs4 and general charts. Here are a few examples from the charts of the website:
PS. If you want help me with the upkeep cost of the server, you can donate. I would really appreciate it!
Special thanks to donators
