Keycloak vs OAuth.io: What are the differences?

  1. User Management: Keycloak provides built-in user management functionality, allowing organizations to manage user accounts, roles, and permissions within the Keycloak platform itself, while OAuth.io does not provide native user management capabilities, requiring integration with external user directories or services for user account management.
  2. Integration Complexity: Keycloak is a standalone open-source Identity and Access Management solution, providing a comprehensive set of features for managing authentication and authorization, while OAuth.io is mainly focused on simplifying OAuth integrations through a unified API, making it easier to integrate OAuth providers into applications.
  3. Customization Options: Keycloak offers extensive customization options for various aspects such as themes, login forms, and user flows, enabling organizations to tailor the user experience to their specific requirements, whereas OAuth.io primarily focuses on standardizing and simplifying OAuth integrations, with limited customization capabilities.
  4. License Model: Keycloak is open-source software distributed under the Apache License 2.0, allowing users to modify and distribute the software freely, while OAuth.io offers a commercial license with pricing based on usage, providing support and additional features for organizations that require extra services.
  5. Single Sign-On Support: Keycloak includes robust Single Sign-On (SSO) capabilities out of the box, enabling users to access multiple applications with a single set of credentials, while integration with OAuth.io may require additional configurations to achieve similar SSO functionality.
  6. Community Support: Keycloak has a large and active community of developers and contributors, providing a wealth of resources, documentation, and community support, whereas OAuth.io may have a smaller community presence due to its focused niche in simplifying OAuth integrations.

In Summary, Keycloak offers comprehensive user management, customization options, and Single Sign-On support, while OAuth.io simplifies OAuth integrations with a focus on integration complexity.

Advice on OAuth.io, Keycloak

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.

OAuth is a protocol that aimed to provide a single secure recipe to manage authorizations. It is now used by almost every web application. However, 30+ different implementations coexist. OAuth.io fixes this massive problem by acting as a universal adapter, thanks to a robust API. With OAuth.io integrating OAuth takes minutes instead of hours or days.

It is an Open Source Identity and Access Management For Modern Applications and Services. It adds authentication to applications and secure services with minimum fuss. No need to deal with storing users or authenticating users. It's all available out of the box.

Quickly integrate API providers; More than 100 providers available; Secured encrypted API; Simplified API calls; Web and mobile SDKs; User and app activity analytics; Request API: perform actions on behalf of users
