Keycloak is an open-source identity and access management (IAM) solution that provides authentication, authorization, and user management for modern applications. It enables developers to secure applications and services without building custom authentication systems, offering features like single sign-on, social login, and user federation.
Developers and organizations building web applications, microservices, or APIs that require secure authentication and authorization, particularly those needing enterprise-grade IAM capabilities without vendor lock-in.
Keycloak offers a fully open-source, self-hosted alternative to commercial IAM platforms with comprehensive protocol support, extensive customization options, and no licensing costs, making it ideal for organizations prioritizing control, flexibility, and cost-efficiency.
