Auth0 by Okta offers a free tier with 7,500 Monthly Active Users (MAUs), but it becomes relatively expensive at higher volumes, costing $1400/month for 20,000 MAUs. AWS Cognito, on the other hand, tends to be more cost-effective for scaling to higher volumes of users, especially when integrated with other AWS services. Therefore, AWS Cognito might be a better choice for handling high volumes of users if cost is a significant factor.
