Features and specs

What each product offers, as listed by its team.

Surfshark 7 features
Cozystack 5 features
  • Affordability
    Surfshark offers competitive pricing and often provides discounts for longer subscription periods, making it a cost-effective VPN solution.
  • Unlimited Devices
    One of Surfshark's unique features is that it allows unlimited simultaneous connections on a single account, supporting families and multiple-device households without extra costs.
  • Strong Encryption and Security Features
    Surfshark employs AES-256-GCM encryption and offers features like CleanWeb (ad-blocking), MultiHop (double VPN), and a Kill Switch for strong online security.
  • No Logs Policy
    Surfshark operates under a strict no-logs policy, ensuring that they don’t track your online activities, which is crucial for privacy-conscious users.
  • Wide Server Network
    With over 3,200 servers in 65 countries, Surfshark provides excellent global coverage for unblocking geographically restricted content.
  • 24/7 Customer Support
    Surfshark offers around-the-clock customer service via live chat and email, providing assistance whenever needed.
  • Bypasser (Split Tunneling)
    This feature allows users to choose which apps or websites go through the VPN and which connect to the internet directly, offering greater flexibility.

Possible disadvantages

  • Newer in the Market
    As a relatively new entrant in the VPN market, Surfshark's long-term reliability and user trust aren't as established as older providers.
  • Inconsistent Speeds
    Some users report variable connection speeds depending on server location and time, which can affect activities like streaming or gaming.
  • Limited Advanced Features
    While Surfshark offers many basic but essential features, it lacks some advanced customization options found in more established VPNs.
  • Fewer Server Locations
    Although it has a wide server selection, some competing VPN services offer more locations, which may impact users needing very specific geographies.
  • 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.
