This is the first large-scale analysis of Grandmaster activity across Chess.com and Lichess from 2008 to 2025, based on years of data collection and millions of games. I explored w…

Hi everyone! ChessMonitor is an analytics platform for chess players that provides stats on your games. The link shows an example of Magnus Carlsen. Connecting your own Chess.com o…

Chess.com Insights are similar to what my project is doing. However, Lichess has nothing similar. They do have something called "Chess Insights" but it's not really comparable IMHO…

Shameless plug: f you're looking for a similar way to compare your online rating with the FIDE rating, take a look at my project: https://www.chessmonitor.com/ Like the author, I a…

Both features are already on my TODO list. That doesn't mean they are coming soon, though... ;)

Thanks, I'll look into this!

That is where some of the inspiration came from. Years ago, I was an avid Dota player and always loved Dotabuff (and OpenDota, too).

Thanks for the feedback! Always good to hear from chess players with a FIDE rating that it's working :) If anyone wants more info on how this works, check out this post with more d…

I'm aware of Chess960, but this will probably never be supported on ChessMonitor for three reasons: First, Chess960 basically tries to prevent players from preparing (by having a r…

There are many similar features. Overall the UI on ChessMonitor is much more focused on statistics. Another key feature Lichess does not have, is the Openings page. It is very powe…

Thanks, I just like it when all state is in the URL and you can just bookmark it. Also using the browser back/forward button should work well thanks to that. I'll check out your li…

I'm currently not doing Stockfish evaluations (everything is based on simple win/loss-rate) but I hope I'm able to integrate this in the future. Then I can show much more in-depth …

Hi everyone, author here. Please let me know if you have feedback or questions.

Yes, in contrast to storing the board (which can be a fixed size), this depends on the length of the game of course. That said, there are some optimizations you can apply that will…

Thanks for your feedback! I guess OAuth is relatively fast as I don't have a middleman (like Auth0) in there. It's just Passport.js.

Yes, ignoring compression each (half-)move takes up one byte. So if you want to store a sequence of 10 (half-)moves it would take only 10 bytes.

Surprisingly, storing a game (with all moves) can take less space than encoding a single board. This is because you can effectively encode a move in a single byte (as there are les…

I created a website to analyze chess games. By connecting your Chess.com/Lichess account you can access all kind of statistics related to your chess games. You can even link more t…

Yes, I've played Dota myself and always loved dotabuff. That's where some of the inspiration came from.

Shameless plug: In case you want to track your chess progress and see more statistics on your openings (win rates, etc.), I'm developing a website where you can link your accounts …

I'm currently developing this: https://www.chessmonitor.com/ It stores your games and gives you an explorer for your games similar to what openingtree does. Here is an example for …

Thanks for the feedback. It's not really a bug. More of a communication problem... ;) The openings page list your openings for white and black. If you click on an opening it takes …

As you say, I currently don't. In the future I might check the correlation between chess.com/lichess (when enough users register). Then I should be able to even calculate the chess…
