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; OVHcloud public Cloud pricing table lists a scheduled price change with a column labeled Price on April 1, 2026, showing current rates are promotional and set to change on that date
  • They diverge on capability: K3s covers Single binary, OVHcloud covers Public Cloud.
  • Prices and features above were last checked on 30 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

OVHcloud

  • Public Cloud pricing table lists a scheduled price change with a column labeled Price on April 1, 2026, showing current rates are promotional and set to change on that date
  • Free network traffic and free Object Storage API calls exclude the Asia-Pacific region

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.

OVHcloud: How does OVHcloud charge for cloud services?

OVHcloud offers pay-as-you-go pricing for compute, storage, and bandwidth. Specific per-unit costs are accessed through the pricing calculator on the vendor site.

Source
K3s: Is K3s real Kubernetes?

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

OVHcloud: Are there savings plans for OVHcloud services?

OVHcloud mentions savings plan options on its services pages, but pricing discounts and commitment terms are not detailed on the homepage.

Source
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.

OVHcloud: What is the cost of OVHcloud zero inter-AZ fees?

OVHcloud advertises zero inter-AZ (availability zone) fees for data transfers within its network. Monthly subscription rates for individual services are not published on the vendor homepage.

Source
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.
