What are restrictions for Free plan?
Free plan has a limit of 2 bots only. You won't be able to create new ones if you have already more than 2 bots and won't be able to turn on more than 2 bots simultaneously.
Free plan doesn’t have any other restrictions, the only difference is the max number of bots. If you already have 2 bots and want to create another one, you would first need to delete at least one bot, to create and launch a new one.
