    Why switch from K3s

    Upstream Kubernetes, assembled yourself or via a managed cloud service, for larger production clusters.

    Pros

    • Industry standard with a huge ecosystem of tools, operators and Helm charts
    • Runs the same way on every major cloud and on your own hardware
    • Self-healing, rolling updates and autoscaling built in

    Cons

    • Steep learning curve and many moving parts to operate
    • No built-in logging, monitoring or CI/CD; you assemble those yourself
    • Overkill for a few small apps on one server

  3. HashiCorp Nomad logo

    3. HashiCorp Nomad

    Best for: Teams that need to schedule containers and legacy apps together without running full Kubernetes

    Free plan + paidSelf-hostableLinux, Windows, macOS, Self-hosted

    64.8

    score / 100

    Why switch from K3s

    Another single-binary scheduler that also runs non-container workloads and is simpler to reason about.

    Pros

    • One binary for servers and clients, so clusters are quick to stand up
    • Runs non-container workloads such as executables, Java and VMs
    • Fits neatly with Consul and Vault for discovery and secrets

    Cons

    • Smaller ecosystem than Kubernetes; Helm charts and operators don't apply
    • Source-available licence rather than open source since 2023
    • Quotas, policy and audit logging need the paid Enterprise edition
