What is Casdoor?

Casdoor is rebuilding its console on shadcn/ui, porting auth features into web2 release by release.

Casdoor tags multiple releases a day, each carrying a single commit, so the version stream reads as a commit log rather than a milestone list. The visible work splits in two: a frontend rewrite called web2 that is absorbing the old antd console into shadcn/ui and re-acquiring features as it goes, and a steady trickle of repairs on the live auth surface covering signup validation, theme handling, and translations. SAML IdP-initiated SSO in v3.161.0 is the only protocol-level addition anywhere in this window.

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.

Casdoor is rebuilding its console on shadcn/ui, porting auth features into web2 release by release.

◆ Current state

Casdoor tags multiple releases a day, each carrying a single commit, so the version stream reads as a commit log rather than a milestone list. The visible work splits in two: a frontend rewrite called web2 that is absorbing the old antd console into shadcn/ui and re-acquiring features as it goes, and a steady trickle of repairs on the live auth surface covering signup validation, theme handling, and translations. SAML IdP-initiated SSO in v3.161.0 is the only protocol-level addition anywhere in this window.

◆ Where it's heading

The web2 migration is the spine of this release train, and it is advancing by increments rather than by cutover: code moves across, then the features that code backed get rebuilt on the other side. Everything else in the window is maintenance on the shipping product, sized to single commits. Expect the migration to keep consuming minor versions until web2 reaches parity with the console it replaces.

◆ Prediction

The next releases most likely continue porting console screens into web2 and cleaning up the login theme path that v3.160.0 and v3.163.3 have both touched. The entries give no signal on when web2 becomes the default, so the cutover timing is unclear.

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.
