Adding on to what Luke said above, Vape V3 and Vape Lite are separate, so you would have to pay for both if you wanted both. Vape Lite has a monthly subscription. ($10 monthly), and Vape V3 has a lifetime subscription ($35 without sale)
If you use Vape on big servers like Hypixel, don't bother getting Vape Lite. Moderators aren't allowed to screenshare your PC on Hypixel, so getting Vape Lite would just be wasting money.
