  • Secure Cloud Storage

  • Download Options
    Allow recipients to download certificates in PDF or digital formats.
  • 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.
