OpenKruise vs Gloo Gateway

OpenKruise vs Gloo Gateway: at a glance
What is OpenKruise?
Seven workload APIs graduated to beta — then the feed went quiet for six months.
OpenKruise's tracked releases stop in January 2026, all of them alphas of v1.9.0. The substantive one moved seven APIs — BroadcastJob, AdvancedCronJob, ImagePullJob, ImageListPullJob, NodeImage, Advanced DaemonSet and SidecarSet — from v1alpha1 to v1beta1, updated the Kubernetes dependency to 1.32.6 and Go to 1.23, and added capability across the workload controllers: reserved unschedulable pods in UnitedDeployment, cron-driven ImagePullJob, deadline handling in CloneSet, and PodUnavailableBudget protection for pod resize. Two of the three entries are the same changelog tagged four minutes apart.
What is Gloo Gateway?
One status-churn fix, shipped to four maintenance branches inside forty minutes.
Gloo maintains four release lines at once — 1.18, 1.19, 1.20 and 1.21 — plus a 1.22 beta series, and fixes are fanned across all of them together. On 5 August, v1.18.41, v1.19.20, v1.20.22 and v1.21.13 were cut within forty-five minutes of each other carrying the same Kubernetes Gateway report-churn fix and the same Go, gRPC and kubectl dependency bumps.

OpenKruise
0.0INFRA · APIS
Seven workload APIs graduated to beta — then the feed went quiet for six months.
◆ Current state
OpenKruise's tracked releases stop in January 2026, all of them alphas of v1.9.0. The substantive one moved seven APIs — BroadcastJob, AdvancedCronJob, ImagePullJob, ImageListPullJob, NodeImage, Advanced DaemonSet and SidecarSet — from v1alpha1 to v1beta1, updated the Kubernetes dependency to 1.32.6 and Go to 1.23, and added capability across the workload controllers: reserved unschedulable pods in UnitedDeployment, cron-driven ImagePullJob, deadline handling in CloneSet, and PodUnavailableBudget protection for pod resize. Two of the three entries are the same changelog tagged four minutes apart.
◆ Where it's heading
This is a project consolidating rather than expanding — graduating APIs to beta is a commitment to stop changing their shape, and the accompanying features fill gaps in existing controllers rather than adding new ones. The pod resize protection is the one forward-looking item, tracking in-place resource resizing as it stabilizes upstream in Kubernetes. Whether the v1.9.0 line ever reached a stable release is not visible here.
◆ Prediction
The obvious next step is a stable v1.9.0 with the v1beta1 APIs finalized. The six-month gap since the last alpha is worth verifying against the project's actual release activity before reading it as a slowdown.
Gloo Gateway
5.0INFRA · APIS
One status-churn fix, shipped to four maintenance branches inside forty minutes.
◆ Current state
Gloo maintains four release lines at once — 1.18, 1.19, 1.20 and 1.21 — plus a 1.22 beta series, and fixes are fanned across all of them together. On 5 August, v1.18.41, v1.19.20, v1.20.22 and v1.21.13 were cut within forty-five minutes of each other carrying the same Kubernetes Gateway report-churn fix and the same Go, gRPC and kubectl dependency bumps.
◆ Where it's heading
The recurring theme is translation correctness under Kubernetes Gateway API — specifically, bugs where the translator's internal state does not behave the way its callers assume. The report-churn fix found equality checks comparing maps of pointer values, so identical output registered as changed on every recompute. The delegateOptions fix in beta11 found RouteOptions assigned by reference from the snapshot, so merging parent Virtual Service options mutated shared protos and contaminated every other route for the rest of the cycle. Both ship with the same instinct for caution: the second one is gated behind GLOO_ISOLATE_DELEGATE_ROUTE_OPTIONS so operators can revert.
◆ Prediction
The 1.22 beta line will keep collecting Gateway API translation fixes ahead of a stable release, and each one that matters will be backported across all four maintenance branches on the same day, as this window shows twice.
