Thanos vs Casdoor
A side-by-side editorial comparison of Thanos and Casdoor — release velocity, themes, recent moves, and the top alternatives to consider.
Thanos vs Casdoor: at a glance
What is Thanos?
Thanos is rebuilding Receive around multi-tenancy, and shipping it through a stuttering RC train.
Thanos is working through the 0.42.0 release candidates, where the headline work is on Receive: tenant lifecycle handling, per-endpoint configuration, and fanout information surfaced in Thanos Query. The line also adopted Go's *os.Root API, which rc.2 exists mainly to clean up after. The release pipeline itself has been unreliable — rc.0 was skipped outright because base image SHA updates broke it, so rc.1 and rc.2 carry identical feature notes.
What is Casdoor?
Ten releases in 48 hours, nearly all of them tightening who can do what, for how long
Casdoor is shipping a one-feature-per-release train at extreme cadence — ten tagged versions across two days, each carrying a single commit. The subject matter is unusually concentrated: seven of the last ten entries touch authorization, session lifetime, or OAuth protocol conformance rather than the UI or the connector surface. What used to be an SSO front-end with a Casbin engine behind it is being reworked at the permission layer itself.

Thanos is rebuilding Receive around multi-tenancy, and shipping it through a stuttering RC train.
◆ Current state
Thanos is working through the 0.42.0 release candidates, where the headline work is on Receive: tenant lifecycle handling, per-endpoint configuration, and fanout information surfaced in Thanos Query. The line also adopted Go's *os.Root API, which rc.2 exists mainly to clean up after. The release pipeline itself has been unreliable — rc.0 was skipped outright because base image SHA updates broke it, so rc.1 and rc.2 carry identical feature notes.
◆ Where it's heading
The centre of gravity is multi-tenant operation. Per-endpoint configuration and tenant lifecycle handling are what an operator needs to run one Thanos install for many teams rather than one per team, and the Query fanout view is the observability that makes such a topology debuggable. The parallel fixes to multi-tier query setups — preserving external label matchers across Query A → Query B → Sidecar chains — point at the same reality: deployments are getting deeper, not just wider.
◆ Prediction
A 0.42.0 stable should follow once the *os.Root regressions settle. The RC notes are cumulative and the feed is quiet since June, so treat cadence here as release-train artefact rather than a slowdown in the project.
Casdoor
5.0INFRA · APIS
Ten releases in 48 hours, nearly all of them tightening who can do what, for how long
◆ Current state
Casdoor is shipping a one-feature-per-release train at extreme cadence — ten tagged versions across two days, each carrying a single commit. The subject matter is unusually concentrated: seven of the last ten entries touch authorization, session lifetime, or OAuth protocol conformance rather than the UI or the connector surface. What used to be an SSO front-end with a Casbin engine behind it is being reworked at the permission layer itself.
◆ Where it's heading
The direction is from standing access toward time-bounded, audience-scoped access. Permissions now carry a configurable expiry that revokes them automatically, token retention is set per organization instead of globally, and the OAuth path preserves RFC 8707 resource indicators so tokens can be bound to a specific target rather than the whole deployment. Alongside that, the enforcement path is being made cheaper — a batch permission API exists specifically to stop rebuilding the Casbin enforcer per call — which is what you build when permission churn stops being an admin-scale event.
◆ Prediction
Expect the expiry work to grow into a policy surface rather than a single field — per-role or per-application default TTLs, and an audit view of what expired when. The batch API and the RFC 8707 handling point the same way, so a first-class machine or service-identity flow is the plausible next step, though nothing in these entries names it directly.
