Features and specs

What each product offers, as listed by its team.

Quad9 5 features
Cozystack 5 features
  • Privacy-Focused
    Quad9 does not store any personal data about users and maintains a stringent privacy policy, ensuring that your DNS queries are not tracked or sold to third parties.
  • Security
    Quad9 provides robust security features by blocking access to known malicious domains, which helps protect users from phishing, malware, and other online threats.
  • Performance
    With a global network of servers, Quad9 offers fast DNS resolution, which can contribute to quicker website load times and improved overall internet browsing experience.
  • Easy to Set Up
    Changing your DNS to Quad9 is straightforward and can be easily configured on most devices without requiring technical expertise.
  • Free Service
    Quad9 offers its DNS services free of charge, making it an accessible option for anyone looking to improve their online privacy and security without additional costs.

Possible disadvantages

  • Limited Customization
    Quad9 does not offer as many customization options as some competing services, which may be a drawback for advanced users looking for more control over their DNS settings.
  • Possible Geolocation Issues
    Using a global DNS resolver like Quad9 can sometimes lead to geolocation issues, where content or services are delivered based on server location rather than user location.
  • Not as Established
    Quad9 is a relatively new entrant in the DNS space compared to longstanding providers like Google Public DNS and OpenDNS, which might make some users hesitant.
  • Dependency on Upstream Filters
    Quad9's security filtering relies on upstream threat intelligence providers. Therefore, the comprehensiveness of the protection is dependent on the accuracy and timeliness of these third-party sources.
  • 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.

    So assuming the answer to a query of what something like dev.to is mainly starts at the locally designated DNS servers. This will most likely be your ISP but it's not uncommon to utilize public DNS servers such as Quad9, Google, and... - Source: dev.to / 5 months ago
