Muse is SO fun to use. Because you get an entire dedicated VM, you can have it host websites for you.

I had it setup a fun website that does nothing but ask my wife what she wants for dinners this week using a bunch of recipes that are popular online. It's setup with the ability for her to quickly edit the recipe ingredients (e.g. ground turkey instead of ground beef), and it's tracking all of her feedback. I'm hoping overtime we start to build a nice set of recipes this way with some new fun ones mixed in on occasion.

For the auth I had it use my messenger app to send her a magic link.
