Casdoor vs Nebula
A side-by-side editorial comparison of Casdoor and Nebula — release velocity, themes, recent moves, and the top alternatives to consider.
Casdoor vs Nebula: at a glance
What is Casdoor?
Casdoor ships a version bump per commit, and the recent run is all tenancy hardening.
Casdoor tags a release on nearly every merge — ten versions between August 4 and August 10, most carrying a single commit. The recent run clusters on two threads: multi-tenant isolation (cross-organization webhook restrictions, organization checks on add APIs, Casbin group rules following user renames) and DingTalk integration repair. Individually each release is small; read together they are a sustained pass over organization boundaries.
What is Nebula?
Overlay network that rewrote its certificate format, then spent a year fixing what it exposed.
Nebula is a peer-to-peer mesh VPN built around a certificate authority model. The v1.10.0 release was the pivot: IPv6 and multiple addresses in the overlay, plus a new v2 ASN.1 certificate format with a unified interface for external implementations. Everything since has been consequence management — a P256 signature malleability issue that allowed blocklist bypass, a source-IP acceptance flaw tied to the new multi-address certificates, and a run of fixes around route tables and Windows listeners.

Casdoor
5.0INFRA · APIS
Casdoor ships a version bump per commit, and the recent run is all tenancy hardening.
◆ Current state
Casdoor tags a release on nearly every merge — ten versions between August 4 and August 10, most carrying a single commit. The recent run clusters on two threads: multi-tenant isolation (cross-organization webhook restrictions, organization checks on add APIs, Casbin group rules following user renames) and DingTalk integration repair. Individually each release is small; read together they are a sustained pass over organization boundaries.
◆ Where it's heading
The organization is becoming the unit of configuration. Record retention days, default token format, master-password hashing and LDAP visibility all became per-organization concerns inside a single week. That is the shape of a project hardening for multi-tenant deployment rather than adding end-user features, and the cross-organization webhook restriction in the newest release is the clearest statement of it so far.
◆ Prediction
Expect the per-organization configuration surface to keep growing and more cross-organization access checks on the remaining endpoints, since the last week has moved steadily in that direction. The per-commit release cadence means this will arrive as another ten small versions rather than one milestone.
Nebula
2.5INFRA · APIS
Overlay network that rewrote its certificate format, then spent a year fixing what it exposed.
◆ Current state
Nebula is a peer-to-peer mesh VPN built around a certificate authority model. The v1.10.0 release was the pivot: IPv6 and multiple addresses in the overlay, plus a new v2 ASN.1 certificate format with a unified interface for external implementations. Everything since has been consequence management — a P256 signature malleability issue that allowed blocklist bypass, a source-IP acceptance flaw tied to the new multi-address certificates, and a run of fixes around route tables and Windows listeners.
◆ Where it's heading
The project has moved from single-IPv4-per-node assumptions toward a genuinely flexible addressing model, and the security fixes since v1.10.0 map directly onto that change — the new certificate features widened what the code has to validate. v1.11.0 shifts attention to the operational surface instead: structured logging, corrected firewall reject-versus-drop semantics, and Windows WFP filters installed by default.
◆ Prediction
The stated plan to assert low-s signature form when validating certificates is the concrete next step visible in these entries; expect it to land as a breaking validation change in a future release.
