Longer forms for Vivi could be Vianne, Viatrix, Vibiana, Vienna/Vienne, Vilma, Vincenza, Viola, Violetta, Viona, Virginia, Virna, Vitalia, Viveca/Viveka, Viviana, Viviane and Viviette.
In my opinion it’s weird to have this name be a nickname for any name besides Vivian or Viviana. Also I like this as a nickname but as a full name it’s trying too hard to be cutesy and different. Why do so many people use this as an online name though?
Besides being used as a Scandinavian diminutive of Olivia and Sofia, Vivi can also be used as a diminutive of Vivian, Viola (as well as other names beginning with Vi), Sofie, Sylvia/Silvia, etc.
I've heard this pronounced viv - vi, like Vivian, and vee- vee. The viv - vi I know is named Vivienne, and the vee - vee is named Genevieve. I love it as a nickname for both, though I prefer the Genevieve pronunciation.
Vivi Nefeltari (previously Nefertari) is the princess of the desert kingdom of Alabasta in the anime/manga One Piece, and temporarily joins the main crew for an arc, and will soon be making a reappearance in said anime/manga.

It's an awesome name. Shout out to my friend Vivi :)
I know someone who is named Genevieve and nicknames herself Vivi, and it really seems like a name that suits her. It is a wonderful nickname for Genevieve, Vivienne, Vivian, or really any name that starts with Vivi.

This sounds kinda cute. It could make a nice nickname for Vivian as well.
