Start free. Upgrade when the limits start getting in your way — and nothing you have built is ever deleted if you move back down.
"Saved items" means automations, redeems, goals, chat rules and uploads — counted separately for each kind. Free allows 3 of each, Plus allows 10, and Connect is unlimited. Every feature is available on every plan except the Connect ones, so you are limited on how much you can save, not on what you can try.
Yes, and there is no time limit or card required. You get every feature except the Connect ones, with a limit of three saved items of each kind.
Nothing you have built is deleted. You keep everything and simply cannot add more until you are back under the limit. Deleting someone's work because they stopped paying would not be right.
Everything in Plus, and the Connect features on top: stream docks, games, Spotify, smart home control and the events API. They are the one part not included on Free or Plus.
Plus gives you 10 saved items of each kind and multi-streaming. Connect makes those unlimited, keeps your full analytics history, and adds the Connect features — stream docks, games, Spotify, smart home and the events API.
At any time. You keep access until the end of the period you have paid for, then move to the free plan — your setup stays where it is.
