Casdoor vs Skipper
A side-by-side editorial comparison of Casdoor and Skipper — release velocity, themes, recent moves, and the top alternatives to consider.
Casdoor vs Skipper: at a glance
What is Casdoor?
Casdoor is spending its release cadence moving auth checks from the client to the server
Casdoor is in a tight patch cadence: six tagged releases inside a week, most carrying a single commit. The substance is concentrated in identity enforcement rather than features - password rotation and MFA setup are now enforced server-side, admin updates to a user respect the column whitelist, sessions and tokens are revoked when a user is forbidden, and phone numbers are normalised before they are stored. The remainder is release plumbing and a PostgreSQL query fix.
What is Skipper?
Zalando's ingress proxy finally speaks HTTP/2 cleartext end to end
Skipper ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.57, which enables h2c on the server handler, the proxy client, and the net client, with a new h2c:// route scheme and Kubernetes appProtocol wiring. Everything else in the window is Dependabot traffic and two narrow fixes to token introspection and grant auth.

◆ Current state
Casdoor is in a tight patch cadence: six tagged releases inside a week, most carrying a single commit. The substance is concentrated in identity enforcement rather than features - password rotation and MFA setup are now enforced server-side, admin updates to a user respect the column whitelist, sessions and tokens are revoked when a user is forbidden, and phone numbers are normalised before they are stored. The remainder is release plumbing and a PostgreSQL query fix.
◆ Where it's heading
Read together, these commits describe one job: closing the gap between what the console enforces and what the backend enforces. Several of them move a check that previously lived in the UI into the server, which is the work of a project being deployed into environments that audit it. New authentication providers and integrations have thinned relative to this hardening pass.
◆ Prediction
The next releases most likely continue the same sweep - remaining endpoints where an admin or user request is trusted more than the server verifies - rather than adding a new identity provider.

Zalando's ingress proxy finally speaks HTTP/2 cleartext end to end
◆ Current state
Skipper ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.57, which enables h2c on the server handler, the proxy client, and the net client, with a new h2c:// route scheme and Kubernetes appProtocol wiring. Everything else in the window is Dependabot traffic and two narrow fixes to token introspection and grant auth.
◆ Where it's heading
The release cadence is a stream of small, individually unremarkable tags where the occasional protocol or load-balancing change is the only thing worth reading. Recent substance has clustered on the data path: leastRequests balancing in v0.27.53, h2c now. The auth filters are being maintained rather than extended, with fixes rather than new capability.
◆ Prediction
Expect the h2c work to generate follow-up fixes as it meets real gRPC backends, since the release notes already show HTTP Upgrade negotiation failing while direct prior knowledge works.
