Features and specs

What each product offers, as listed by its team.

Cemu 5 features
Cozystack 5 features
  • High Performance
    Cemu offers high performance and can run games at higher resolutions and frame rates than the original Wii U console.
  • Compatibility
    It has a high compatibility rate with a large library of Wii U games, allowing users to play a wide range of titles.
  • Graphical Enhancements
    Cemu allows for significant graphical improvements, including anti-aliasing, anisotropic filtering, and custom shaders.
  • Frequent Updates
    The development team regularly updates Cemu to fix bugs, add new features, and improve overall performance.
  • Community Support
    A strong community provides plenty of support, mods, and resources to enhance the gaming experience.

Possible disadvantages

  • Complex Setup
    The initial setup can be complicated for those unfamiliar with emulators and may require additional configuration to get games running optimally.
  • Hardware Demands
    Cemu can be resource-intensive and requires a relatively powerful computer to run games smoothly, especially at higher settings.
  • Legal Issues
    Using Cemu may involve legal concerns, as running the emulator requires dumping game files and firmware from a Wii U, which may not be straightforward or within legal boundaries for all users.
  • Inconsistent Game Performance
    Not all games run perfectly on Cemu, with performance varying greatly between different titles and requiring tweaks for optimal experience.
  • Limited Controller Support
    Some users might experience challenges when configuring controllers, especially if they want to replicate the Wii U's unique gamepad features.
  • 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.
