My Anime List
Track anime. You can customize your profile and your lists. You can have a couple favorites in each category.
Anilist
Like MAL but tends to have a larger database. More people contribute to this, in general. The UI is awful and very ugly so that's why I left. You can have as many favorites as you would like and there is more of a focus on the social element. A useful tool to use is shared faves which you can run on other Anilist profiles to see if you share favorites.
Sakugabooru
A gallery of cool animations. It can be fun to go through and useful in deciding if you want to watch something or not that you've heard of.
Caracal.club
You can use this to watch anime with your friends online. Or whatever you really want to, for that matter.
Misc.
My Figure Collection
Keep track of your own merch collection, see news, community updates, and browse a library of documented merch. If you like older stuff though, you will have to be prepared to do some uploading to the site itself.
Visual Novel Database
Well maintained and organized library of everything Visual Novels.
AMQ (Anime Music Quiz)
A game where you try to guess what anime a song is from. Very popular so you can always find someone to play with.
