There is no definitive answer to this question as it depends on the definition of “free” used. Generally speaking, a blogging platform that is free to use means that there are no charges incurred for using the platform. However, this is not always the case with free blogging platforms.
For example, Wix requires users to register and create an account before they can start using the platform. However, users do not have to pay any fees to use the platform once they have registered.
Ultimately, it is important to consider the terms of service of a free blogging platform before making a decision about whether or not it is free. If the platform requires users to register and sign up for a subscription in order to use certain features, then it may not be considered free by some people.
