What are restrictions for Free plan?

Free plan has a limit of 5 bots only. You won't be able to create new ones if you have already more than 5 bots and won't be able to turn on more than 5 bots simultaneously.

Free plan doesn’t have any other restrictions, the only difference is the max number of bots. If you already have 5 bots and want to create another one, you would first need to delete at least one bot, to create and launch a new one.
