The short version

  • Only K3s has a free tier, so it costs nothing to try first.
  • Each has a real cost: K3s the SQLite default is single-server only; highly available control planes need etcd or an external datastore, which removes much of the simplicity; Orca Security no public pricing; requires a demo and custom quote from sales.
  • They diverge on capability: K3s covers Single binary, Orca Security covers Agentless cloud scanning.
  • Prices and features above were last checked on 29 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

K3s

  • The SQLite default is single-server only; highly available control planes need etcd or an external datastore, which removes much of the simplicity
  • Bundled components such as Traefik are opinionated defaults that larger teams often strip out and replace
  • Removed in-tree cloud provider integrations mean cloud-specific features need external controllers
  • Aimed at small and edge clusters, so very large deployments are better served by a standard distribution

Orca Security

  • No public pricing; requires a demo and custom quote from sales.
  • Agentless-only scanning may miss some runtime telemetry that agent-based tools capture.
  • Full value depends on integrating many of the platform's modules across code, cloud, and AI.
  • Primarily targeted at mid-to-large organizations with multi-cloud environments.

Answered from the vendors’ own pages

K3s: Is K3s free?

Yes. K3s is open source with no licence fee. SUSE sells commercial support around Rancher separately.

Orca Security: How much does Orca Security cost?

Orca Security does not publish pricing tiers or rates on their website. Organizations must contact Orca Security directly or request a demo to receive custom pricing information based on their specific use case and requirements.

Source
K3s: Is K3s real Kubernetes?

Yes. It is CNCF-certified conformant, so standard manifests, kubectl and Helm charts work without modification.

K3s: Why is K3s smaller than Kubernetes?

It strips legacy, alpha and in-tree cloud provider code, packages everything as one binary, and defaults to SQLite instead of etcd.

K3s: Can K3s run in production?

Yes, and it does, particularly at the edge and for small clusters. For a highly available control plane you need to move off the SQLite default to etcd or an external datastore.
