I’m not the parent commenter, but I use Lichess. It’s free, supported by donations (so their incentives align with mine more than a business’), open source (which I like ideologically), and in my opinion just has a nicer user interface.
I started playing chess online less then a month ago. I started with chess.com, because I knew about it beforehand for some reason. After about a week there I couldn’t take their constant nagging about getting premium account: “Get a free 7 day trail”, “Get a premium account to unlock more analysis”, “you’ve reached your maximum puzzles for the day, get a premium subscription to unlock more”, etc.
I did some research (mostly on the online-go.com forums) and joined lichess.org and haven’t looked back since. Superior in every way.
Perhaps I should thank chess.com for being so annoying, if it weren’t for their constant nagging I would probably have stayed on the platform and never discovered lichess.org.
