k3s vs OKD
Both are alternatives to Red Hat OpenShift. Here's how they stack up — verified facts, no spin.
Also searched as OKD vs k3s — same comparison, one verdict.
k3s
TOP PICKCertified Kubernetes in a single small binary — no platform tax.
The most-adopted lightweight Kubernetes: one ~70 MB binary, a cluster in minutes, CNCF-certified conformance, and a huge community. Born for edge, now running everywhere teams decided they need Kubernetes itself rather than a platform wrapped around it.
OKD
OpenShift's free upstream — the same platform, licensing fees removed.
OKD is what OpenShift is built from: the console, builds, routes, and operator model, free and open-source. It's the direct answer to 'we like OpenShift, we don't like the bill.' The honest trade: bleeding-edge releases that break things, community-only support, and upgrades that demand attention.
