Saph's Vanilla is purely a 1.8.9 modpack that enhances the UI and adds a few tools like maps. It is made to work on any vanilla server, including Realms.
I have also included a couple of resource packs. Xaiwaker and Visibility. Both look good. They make it look cartoony, which is the way I like to play Minecraft when I use a resource pack. Reality is for... other people. ;)
Very simple. Very vanilla. Enjoy!
