Does Altura charge a monthly fee?

Could you please clarify for me if Altura imposes any monthly charges on its users? It's important for me to understand the cost structure associated with utilizing the platform's services, and whether there are any recurring fees that need to be considered in my budgeting. I'm particularly interested in knowing if there's a standard monthly fee that applies across the board, or if the charges vary based on factors such as usage, account type, or other criteria. Thank you for your assistance in clarifying this matter.
