3. K3s
Best for: Home labs, edge devices and small clusters that want real Kubernetes with little overhead
Open sourceSelf-hostableLinux, Self-hosted
64.8
score / 100
Why switch from Red Hat OpenShift
A free, lightweight certified Kubernetes that is much cheaper and simpler to run on modest hardware.
Pros
Installs in one command and runs as a single small binary
Certified Kubernetes, so kubectl, Helm and manifests work as usual
Runs well on ARM boards like the Raspberry Pi
Cons
Linux only; no native Windows or macOS server
Still Kubernetes underneath, so the concepts and learning curve remain
Large production estates often need a fuller distribution or managed service

61.8
score / 100
Why switch from Red Hat OpenShift
A simpler scheduler that also handles VMs and legacy binaries, with a paid enterprise tier if needed.
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
