Umami looks great, I just sent it to my wife who just uses Apple notes for recipes right now. I’m curious, how can you offer it for free while having server side processing / syncing etc?
It's few enough users right now that I can cover the couple bucks per month in server costs. If more people start to use it, I'll make it paid (either upfront or subscription, not sure yet), but I'll grandfather all existing users as free.
