It's free.
Everything works, nothing is metered, and there's no upgrade button to find. That will change eventually — but not into the part that lets your friends in.
All of it. No asterisk.
Start a pod and add your regulars. Invite them by link. Run game nights. Build decks and give them pages. Keep every night, every record and every recap, at a real address you can hand to anyone. There is no tier above this one, so there is nothing being held back from you.
Nobody at your table needs an account for you to record a night — only to own their own page.
What we'd charge for, when we charge for something.
Honestly: not decided. The likely shape is that keeping a pod's history and pages online forever costs something to run, so the paid line lands somewhere around depth — longer history, more of it, a pod that looks like yours rather than ours.
What it won't be is the number of pods you can be in, or the number of people you can invite. Charging for that would mean charging you for bringing your friends, which is a strange way to run a thing about playing with your friends.
If that ever changes, it changes on this page first, and pods that were here before it changes keep what they have.
