Features and specs

What each product offers, as listed by its team.

Keycloak 5 features
Cozystack 5 features
  • Open-Source
    Keycloak is an open-source identity and access management solution, which means it is free to use and has a community-driven support system. This can lead to lower costs and more flexibility compared to proprietary solutions.
  • Feature-Rich
    Keycloak offers a comprehensive set of features including single sign-on (SSO), multi-factor authentication (MFA), user federation, identity brokering, and social login. This makes it suitable for a wide range of use cases.
  • Customizability
    With Keycloak, you can customize the authentication and authorization processes through its extensible architecture, allowing for the addition of custom features and integrations.
  • Integration Capability
    Keycloak supports integration with various protocols such as OAuth 2.0, OpenID Connect, and SAML, making it versatile for integrating with different platforms and services.
  • Active Community
    Keycloak has an active and growing community of developers and users who contribute to its improvement and provide support, resources, and shared knowledge.

Possible disadvantages

  • Complexity
    Keycloak can be complex to set up and configure, especially for users who are not familiar with identity and access management concepts. This may require additional time and expertise.
  • Resource-Intensive
    Running Keycloak can be resource-intensive, requiring more CPU and memory compared to simpler authentication solutions. This may necessitate higher infrastructure costs.
  • Learning Curve
    The learning curve for Keycloak can be steep for new users due to its wide range of features and configuration options. Ample time might be required to fully understand and utilize its capabilities.
  • Documentation Quality
    While Keycloak has extensive documentation, some users find it to be insufficiently detailed or difficult to navigate, which can impede the setup and troubleshooting process.
  • Maintenance
    Operating a Keycloak instance involves ongoing maintenance tasks such as updates, security patches, and backups, which can be time-consuming and require dedicated resources.
  • Free and Open Source
    Cozystack is a fully open-source platform (under Apache 2.0 license) built on top of proven open-source technologies like Kubernetes, Talos Linux, and FluxCD, allowing users to inspect, modify, and contribute to the codebase without vendor lock-in.
  • All-in-One PaaS/IaaS Platform
    Cozystack provides a comprehensive platform that combines PaaS and IaaS capabilities, offering managed Kubernetes clusters, databases (PostgreSQL, MySQL, Redis, etc.), virtual machines, load balancers, and monitoring out of the box, reducing the need for multiple separate tools.
  • Built on Battle-Tested Technologies
    The platform leverages well-established cloud-native technologies such as Kubernetes, KubeVirt for virtualization, Kamaji for managed Kubernetes, and Cilium for networking, providing a solid and reliable foundation rather than reinventing the wheel.
  • Simplified Bare-Metal Deployment
    Cozystack is designed to be installed directly on bare-metal servers using Talos Linux, making it relatively straightforward to set up your own cloud infrastructure without needing pre-existing cloud providers or complex manual configurations.
  • GitOps-Driven and Declarative Management
    Using FluxCD and Helm charts under the hood, Cozystack follows GitOps principles, enabling declarative infrastructure management, reproducible deployments, and easy customization of platform components through a standardized workflow.

Possible disadvantages

  • Steep Learning Curve
    Cozystack requires solid knowledge of Kubernetes, Talos Linux, networking, and various cloud-native technologies. Users unfamiliar with these ecosystems may find the initial setup and ongoing management challenging.
  • Relatively Young and Small Community
    Compared to established platforms like OpenStack or major managed Kubernetes services, Cozystack has a smaller user community, which means fewer community-contributed resources, tutorials, third-party integrations, and slower issue resolution from peers.
  • Limited Enterprise Support and Ecosystem
    As a relatively new open-source project, Cozystack lacks the extensive enterprise support contracts, professional services, and partner ecosystems that more mature platforms offer, which may concern organizations requiring SLA-backed support.
  • Hardware and Infrastructure Requirements
    Cozystack is designed for bare-metal deployments and requires a minimum cluster of nodes with specific hardware capabilities (e.g., for KubeVirt virtualization), which may not be accessible or cost-effective for smaller teams or those without dedicated infrastructure.
  • Limited Documentation and Maturity
    Being a newer project, the documentation can be sparse or incomplete in certain areas, and some features may still be evolving, potentially leading to breaking changes or gaps in functionality compared to more mature alternatives.
