The short version

  • 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; Puppet no pricing published for commercial tiers; requires contacting sales
  • They diverge on capability: K3s covers Single binary, Puppet covers Manifests.
  • 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

Puppet

  • No pricing published for commercial tiers; requires contacting sales
  • Enterprise and Advanced tiers require custom quote
  • Free tier limited to 25 nodes maximum

Both have a free tier, so you can try either at no cost before committing.
What is K3s best used for?
K3s is most often used for kubernetes on edge sites and iot hardware where full clusters will not fit, development and ci clusters that must start fast and cost nothing, small production clusters where full kubernetes is more operations than the workload justifies, teaching and learning kubernetes without cloud spend.

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.

Puppet: How much does Puppet cost?

Puppet's Developer tier is free for up to 25 nodes. Commercial, Enterprise, and Advanced tiers require contacting their sales team for a custom quote.

Source
K3s: Is K3s real Kubernetes?

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

Puppet: Is there a free version of Puppet?

Yes, Puppet's Developer tier is free forever for up to 25 nodes of infrastructure.

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.

Puppet: What does the Enterprise tier include?

Puppet's Enterprise tier includes web GUI, RBAC, and multi-environment support for organizations managing infrastructure at scale, with pricing available upon request.

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.
