Amazon Cognito is better integrated with the AWS ecosystem, making it a great choice if you are already using AWS services. It offers a generous free tier and a low price per monthly active user, making it cost-effective as you scale. However, its documentation can be confusing and it can be difficult to set up. Keycloak, on the other hand, is an open-source solution that supports various identity providers like Google, Facebook, and GitHub. It may be more suitable if you prefer an open-source approach and need flexibility in identity provider integration.

Amazon Cognito offers a generous free tier with 50,000 monthly active users (MAUs) and a low price for additional users, making it cost-effective as you scale. The cost per additional MAU starts at $0.0055/month and can go down to $0.0025/month for tens of millions of users. Keycloak is open-source and free to use, but the total cost of ownership will depend on the infrastructure and maintenance costs. If you are already using AWS services, Cognito may be more cost-effective due to its seamless integration.

Amazon Cognito can be difficult to set up and its documentation can sometimes be confusing and misleading. Keycloak, being an open-source solution, may require more initial setup and configuration, but its community and extensive documentation can help mitigate this. The ease of setup will largely depend on your familiarity with the respective platforms and your specific requirements.

The pros of Amazon Cognito include its generous free tier, low price per monthly active user, and seamless integration with the AWS ecosystem. However, users have reported that the documentation can be confusing and sometimes misleading, and setting up the service can be difficult.
