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; Teleport pricing is not published and is described as active users plus protected resources, so an autoscaling estate cannot forecast the bill and finance teams discover the true cost only after the first true-up.
  • They diverge on capability: K3s covers Single binary, Teleport covers Short-lived certificates.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

K3s

  • Kubernetes on edge sites and IoT hardware where full clusters will not fitnot Teleport
  • Development and CI clusters that must start fast and cost nothingnot Teleport
  • Small production clusters where full Kubernetes is more operations than the workload justifiesnot Teleport
  • Teaching and learning Kubernetes without cloud spendnot Teleport

Teleport

  • Removing long-lived SSH keys and shared database passwords so that offboarding an engineer takes one action in the identity providernot K3s
  • Producing session recordings and per-user database audit trails as direct evidence for SOC 2 or FedRAMPnot K3s
  • Giving contractors or on-call engineers time-boxed, approved access to production instead of standing admin rightsnot K3s
  • Replacing a flat VPN with per-resource authorisation across servers, Kubernetes and internal web appsnot K3s

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

Teleport

  • Pricing is not published and is described as active users plus protected resources, so an autoscaling estate cannot forecast the bill and finance teams discover the true cost only after the first true-up.
  • The proxy is a hard dependency on reaching production, so it needs its own high availability deployment and a tested break-glass path or an outage in Teleport becomes an outage in your ability to respond to outages.
  • The open source Community Edition omits Access Requests, Device Trust and the FIPS builds, which are exactly the controls an auditor asks about, so the free tier rarely survives a compliance review.
  • Self-hosting means running and upgrading a certificate authority and its backing store, and Teleport releases frequently enough that upgrade work becomes a standing operational commitment.
  • Coverage across protocols is uneven in depth, so teams with legacy systems, unusual databases or bespoke network appliances find gaps that still require the old VPN to remain in place alongside it.

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.

Teleport: Is the open source edition usable in production?

Yes, but it lacks Access Requests, Device Trust and FIPS builds, which most compliance programmes end up requiring.

K3s: Is K3s real Kubernetes?

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

Teleport: How is it priced?

Not publicly. The vendor prices on active users and protected resources and provides a quote after a sales conversation.

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.

Teleport: What happens if Teleport goes down?

Nobody reaches the resources behind it, so you need a highly available deployment and a documented break-glass procedure.

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.

Teleport: Does it replace our VPN?

For anything you put behind it, yes. Legacy systems and appliances it does not support will keep the VPN alive.
