Why switch from Red Hat OpenShift
Free upstream Kubernetes, run yourself or through a cloud provider's managed service, without the subscription.
Pros
- Industry standard with a huge ecosystem of tools, operators and Helm charts
- Runs the same way on every major cloud and on your own hardware
- Self-healing, rolling updates and autoscaling built in
Cons
- Steep learning curve and many moving parts to operate
- No built-in logging, monitoring or CI/CD; you assemble those yourself
- Overkill for a few small apps on one server

3Best for: Home labs, edge devices and small clusters that want real Kubernetes with little overhead
Open sourceSelf-hostableLinux, Self-hosted
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

- Hundreds of one-click self-hosted services
Cons
- You manage server security, updates and uptime
- Small core team
- Multi-server setups take more care than a managed PaaS
