k0s vs Skipper
A side-by-side editorial comparison of k0s and Skipper — release velocity, themes, recent moves, and the top alternatives to consider.
k0s vs Skipper: at a glance
What is k0s?
k0s writes the etcd certificate fix once and backports it down every branch
k0s ships version-only tags across four concurrent support branches, each a roll-up of backported pull requests and image bumps. The 1.36 branch has just taken Kubernetes 1.36.4 together with etcd certificate renewal for clusters using a custom etcd CA, a fix stopping k0s reset from unmounting the kubelet root directory, and image bumps for containerd, Calico, CoreDNS, Traefik and kine. The same etcd certificate work reached the 1.35 branch the same morning.
What is Skipper?
Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.
Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.

◆ Current state
k0s ships version-only tags across four concurrent support branches, each a roll-up of backported pull requests and image bumps. The 1.36 branch has just taken Kubernetes 1.36.4 together with etcd certificate renewal for clusters using a custom etcd CA, a fix stopping k0s reset from unmounting the kubelet root directory, and image bumps for containerd, Calico, CoreDNS, Traefik and kine. The same etcd certificate work reached the 1.35 branch the same morning.
◆ Where it's heading
This is a maintenance distribution doing maintenance deliberately: a fix is written once and lands on 1.34, 1.35 and 1.36 within hours, with a bot authoring most of the roll-up. The two items in this batch that reach operators are both about not breaking a running cluster — certificates that would otherwise expire under a custom CA, and a reset path that was unmounting a directory it did not own. Feature work belongs to upstream Kubernetes; what k0s contributes is the packaging and the safety of the lifecycle commands around it.
◆ Prediction
Expect the branch-parallel pattern to continue, with the next Kubernetes patch releases arriving on 1.34, 1.35 and 1.36 in close succession rather than any one branch pulling ahead.

Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.
◆ Current state
Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.
◆ Where it's heading
The Redis L2 integration suggests the Skipper team is addressing the multi-replica cache coherence problem that large deployments encounter. If this pattern continues, distributed-state options—persistent rate limiting, distributed circuit breakers using the same Redis client abstraction—are the natural follow-ons. The high patch cadence signals active production deployment rather than feature-driven development.
◆ Prediction
The Redis client abstraction introduced in v0.27.92 will be extended to other stateful filters, particularly rate limiting, given that distributed rate limiting is the most common request for API gateways running at multi-replica scale.
