# Agents vs Users

Agents are Feederloop users who can make and receive calls or access voice messages from visitors of your website(s). Subscriptions are billed based on the number of agents you have. Details on pricing can be found here (opens new window).

A user is someone who can log in to your account who is not necessarily an agent. You can add as many users to your account for free as you wish. Users can be assigned specific permissions allowing them to manage teams, users, billing and integrations.
