Is zigzag free?

Excuse me, could you please clarify for me if the platform or service known as "zigzag" is available to users without any cost? I'm specifically interested in whether there are any fees associated with its usage, be it a one-time charge, subscription fee, or transaction costs. Understanding the financial implications of this platform is crucial for me to make an informed decision about whether to adopt it for my needs. Thank you for your time and assistance in clarifying this matter.
