Overview​

A multi-tenant application is a software architecture where a single instance of an application serves multiple, distinct customer groups or “tenants.” Each tenant, often representing an organization or user group, shares the same underlying infrastructure and codebase but operates within its own securely isolated environment. This allows each tenant to have individualized data, configurations, and sometimes even unique customizations, while benefiting from a shared platform that reduces overall resource demands and maintenance. Multi-tenancy is commonly used in SaaS (Software as a Service) applications, enabling businesses to scale efficiently, lower costs, and streamline updates while ensuring that each tenant’s data and settings remain private and distinct from others within the same application. This approach is particularly valuable in enterprise applications, where companies may need to provide access to different organizations, departments, or customer groups within a single solution.

Part 3: Customizability for Tailored Solutions: Why Keycloak Stands Out​

One size rarely fits all, especially in the world of enterprise software. Startups require flexibility to adapt and tailor IAM solutions to their unique business requirements. Keycloak shines in this aspect, offering extensive customization capabilities that empower startups to mold the platform according to their specific needs.

From branding and user interface customization to advanced authentication flows and authorization policies, Keycloak provides a comprehensive toolkit for startups to craft seamless and secure user experiences. Whether integrating with existing systems or building entirely new functionalities, Keycloak's flexibility ensures a perfect fit for any enterprise SaaS startup. Here’s how Keycloak’s flexibility stands apart from commercial, closed-source solutions, and why this is a key differentiator:

Keycloak and Native Applications​

Native applications for iOS, Android, and other platforms can integrate with Keycloak to provide secure, centralized authentication and authorization services. By utilizing Keycloak, these applications can streamline the user login experience through various protocols such as OAuth 2.0 and OpenID Connect, which Keycloak natively supports. With Keycloak, mobile applications can handle user sign-in, token management, and session handling securely, ensuring user identities are managed consistently across devices and platforms. This setup enables native applications to offload the complexities of authentication to Keycloak, allowing seamless integrations with features like Single Sign-On (SSO), social logins, and multi-factor authentication, while developers can focus on app functionality rather than handling sensitive user data directly. Additionally, Keycloak’s support for fine-grained access control and roles ensures that native apps can manage user permissions efficiently, creating a robust foundation for secure, scalable mobile applications.

Part 2 - Owning Your Data: Security, Privacy, and Control​

In the age of data breaches and privacy concerns, owning and controlling your user data is not just a preference but a strategic imperative for organizations, particularly when it comes to Identity and Access Management (IAM) solutions. Let's explore the reasons why owning your data matters and the risks associated with entrusting it to a Software-as-a-Service (SaaS) solution.

Part 1: Standardized Protocols and Minimal Feature Set Differentiation​

In the realm of Identity and Access Management (IAM) solutions, it's essential to recognize that many offerings, both commercial and open source, operate on standardized protocols such as OpenID Connect (OIDC), Security Assertion Markup Language (SAML), System for Cross-domain Identity Management (SCIM), Lightweight Directory Access Protocol (LDAP), and more. This adherence to standardized protocols often results in minimal differentiation at the feature set level across various options. Let's delve into this further:

In the ever-evolving landscape of Enterprise SaaS, navigating the complexities of identity and access management (IAM) can be a daunting task. As a startup striving for excellence in user experience and security, choosing the right IAM solution is paramount. Enter Keycloak, a powerful open-source IAM tool that not only meets but exceeds the demands of modern startups.

Our pal over at Keycloakify has been working on creating a simple OpenId Connect (OIDC) library called, OIDC Spa. As with Joseph's usual approach to user friendliness, OIDC SPA simplifies a lot of the integration work than can come with adding an Authentication and Authorization layer to your application. Follow along as we show you how to integrate OIDC SPA with a Phase Two's free Keycloak instance.

Phase Two has long been big fans of Keycloakify. The work being done by Joseph Garrone is in our opinion some of the best user-focused work in the Keycloak community. Keycloakify brings the ability to theme the Keycloak frontend applications: Login, Account, Admin(coming) using modern toolsets like React or Angular and theming systems like Tailwind or Material-UI. Keycloakify allows you to build quickly and deploy themes to your Keycloak installation in a manner that the existing Keycloak toolset (ftl templates) does not.

We recently gave a talk at the Keyconf24 conference in Vienna on how to extend Keycloak using its extensible SPI structure. In addition to showing what is possible and how to get started in building extensions, we also use our Events and Webhooks extension as a real-world example. The hosts of the conference have posted the video of the talk on Youtube.

Keycloak and Frontegg are two prominent solutions in the identity and access management (IAM) space, each serving distinct needs. Keycloak is an open-source IAM solution with over eight years of development, known for its scalability and deep customization options, allowing organizations full control over user identity management. On the other hand, Frontegg is a cloud-native platform designed for quick deployment and integration, specifically tailored for SaaS applications, offering a user-friendly management experience. In this blog post, we will compare Keycloak and Frontegg based on cost structure, deployment options, customization, scalability, functionality, and support.
