OpenKruise vs Casdoor: 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 Casdoor?
Casdoor is turning single-tenant SSO into per-organization governance, one small release at a time
Casdoor ships multiple tagged releases a week, each carrying one or two commits, with version-only titles that hide the work. The current cluster is governance plumbing: configurable record and token retention per organization, auto-revoking permissions after an expiry window, and a batch UpdatePermissions API that cuts how often the Casbin enforcer rebuilds. Alongside it runs steady OAuth/OIDC conformance work — RFC 8707 resource indicators preserved through fast auto-signin, a backchannel logout URL on the application edit page.

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.
Casdoor
5.0INFRA · APIS
Casdoor is turning single-tenant SSO into per-organization governance, one small release at a time
◆ Current state
Casdoor ships multiple tagged releases a week, each carrying one or two commits, with version-only titles that hide the work. The current cluster is governance plumbing: configurable record and token retention per organization, auto-revoking permissions after an expiry window, and a batch UpdatePermissions API that cuts how often the Casbin enforcer rebuilds. Alongside it runs steady OAuth/OIDC conformance work — RFC 8707 resource indicators preserved through fast auto-signin, a backchannel logout URL on the application edit page.
◆ Where it's heading
The center of gravity has moved from 'can users sign in' to 'can an operator govern what happens after they do.' Retention windows, permission expiry, and rename-safe Casbin group rules are all multi-tenant administration concerns, and each is being made configurable per organization rather than per deployment. The Casbin enforcer rebuild cost surfacing as its own fix suggests these installs are getting large enough for permission-model performance to matter.
◆ Prediction
Expect more per-organization lifecycle policy knobs and continued work on Casbin enforcer performance, since both themes have produced several releases in the last week alone.
