I personally use Kitsu.io because I've difficulties running Anilist smoothly. But if you use either of those two and watch anime with a player rather than via streaming, for convenience's there's also the software Taiga allows you to keep easier automatic track of the anime you're watching and the episodes you're on. It's been running decently for me so far with only a couple issues occasionally.
Recommending it in case you're like me and you only remember to update your lists every two months...
