what maximum capacity of gb can I host among all my repositories whith the POR plan and the FREE plan?
We don’t have a specific limit for the total size of all repositories on an account. To make sure we can give everyone on GitHub a fast, consistent experience, we need to make sure individual repositories are 1 GB at the most. Additionally, you may want to review the Acceptable Use section of our Terms of Service for additional restrictions.
I hope that helps!
