I game on multiple computers and would love to sync addons between them instead of downloading them over and over.
I remember the Twitch addion manager used to do that. Any newer ones do that?
Twitch sold their addon manager to Overwolf. And that seems to be connected to Curse Forge. So maybe give Curse Forge a try, i’ve not looked into it personally.
Something else you could try is saving your Interface/Addon (and maybe WTF) folder(s) into the cloud, e.g. Google drive. Again not tried it, but could be a solution.
