Firebase Authentication vs Keycloak: What are the differences?

Key Differences: Firebase Authentication vs Keycloak

Firebase Authentication and Keycloak are both popular identity management systems used for authentication and authorization. While they share some similarities, there are several key differences between the two platforms.

  1. Integration with Platform Ecosystem: Firebase Authentication is a service provided by Google that seamlessly integrates with other Firebase products, such as Firebase Realtime Database and Firestore. On the other hand, Keycloak is an open-source identity and access management solution that can be integrated with various platforms and technologies, making it more flexible and compatible with different ecosystems.

  2. Deployment Options: Firebase Authentication is a fully managed service provided by Google, which means that it requires minimal setup and maintenance efforts. Keycloak, on the other hand, can be self-hosted, allowing organizations to have full control over their authentication infrastructure and tailor it to their specific needs. This can be advantageous for organizations that require more customization and control over their authentication processes.

  3. Scalability and Performance: Firebase Authentication benefits from Google's robust infrastructure, meaning that it can handle high traffic volumes and offers excellent scalability and performance. Keycloak's performance, on the other hand, may depend on the hardware and setup of the hosting environment, making it potentially less scalable for organizations with significant scalability requirements.

  4. Development Resources and Community Support: Firebase Authentication is backed by Google, one of the largest technology companies, which ensures a vast pool of resources, extensive documentation, and strong community support. Keycloak, being an open-source project, also has a strong community of developers contributing to its development and providing support. However, the level of available resources and community support may vary compared to Firebase Authentication.

  5. Pricing Model: Firebase Authentication is part of the Firebase suite of products and follows a pay-as-you-go pricing model, which is based on the number of active users. Keycloak, being an open-source solution, is free to use, but organizations need to consider the cost associated with self-hosting, maintenance, and support.

  6. Customization and Extensibility: Firebase Authentication provides a streamlined and easy-to-use interface, which allows for quick integration into applications. It offers pre-built UI components and customizable branding options. Keycloak, being an open-source and self-hosted solution, offers greater customization and extensibility options, allowing organizations to tailor the authentication process according to their specific requirements.

In summary, Firebase Authentication is a Google-backed, managed service that seamlessly integrates with the Firebase platform, offers high scalability and performance, and provides extensive resources and support. Keycloak, on the other hand, is an open-source, customizable solution that offers greater flexibility in terms of deployment options and integration with different ecosystems, but requires more effort and expertise for setup and maintenance.

Advice on Keycloak, Firebase Authentication

Needs advice

I am working on building a platform in my company that will provide a single sign on to all of the internal products to the customer. To do that we need to build an Authorisation server to comply with the OIDC protocol. Earlier we had built the Auth server using the Spring Security OAuth project but since in Spring Security 5.x it is no longer supported we are planning to get over with it as well. Below are the 2 options that I was considering to replace the Spring Auth Server.

  1. Keycloak
  2. Okta
  3. Auth0 Please advise which one to use.
