Casdoor vs simDAG
A side-by-side editorial comparison of Casdoor and simDAG — release velocity, themes, recent moves, and the top alternatives to consider.
Casdoor vs simDAG: at a glance
What is Casdoor?
An identity platform tightening server-side enforcement one micro-release at a time.
Casdoor is a self-hosted single sign-on and identity management service covering OAuth, LDAP, MFA and user administration. It releases continuously — four tags landed within eighty minutes on 16 August — with each carrying a single commit, so a version number here marks one change rather than a bundle.
What is simDAG?
simDAG grew a second simulation engine, then spent two releases surviving upstream breakage.
simDAG generates data from directed acyclic graphs, with a library of node types covering Gaussian, binomial, Poisson, negative binomial, zero-inflated, ordered regression, Cox, and Aalen models. The 1.0.0 milestone opened node_cox() to arbitrary baseline hazard functions, which lets continuous time-dependent hazards drive discrete-event simulations. The two most recent releases exist only to keep the package on CRAN through breakage in lme4 and simr.
Casdoor vs simDAG: editorial side-by-side
Casdoor
5.0INFRA · APIS
An identity platform tightening server-side enforcement one micro-release at a time.
◆ Current state
Casdoor is a self-hosted single sign-on and identity management service covering OAuth, LDAP, MFA and user administration. It releases continuously — four tags landed within eighty minutes on 16 August — with each carrying a single commit, so a version number here marks one change rather than a bundle.
◆ Where it's heading
The recent run is almost entirely about moving enforcement to where it cannot be bypassed. Password update and MFA setup are now enforced server-side, the column whitelist is respected when an admin updates a user, and sessions and tokens are revoked when a user is forbidden. Each of these closes a gap where the client or an administrative path could sidestep a rule the product already claimed to apply. LDAP search by uidNumber and gidNumber and phone number normalisation round out the same period.
◆ Prediction
Expect the per-commit release cadence to continue, with further authorization-boundary fixes given three of the last five entries address exactly that. Nothing here signals a larger architectural change.
simDAG
2.5INFRA · APIS
simDAG grew a second simulation engine, then spent two releases surviving upstream breakage.
◆ Current state
simDAG generates data from directed acyclic graphs, with a library of node types covering Gaussian, binomial, Poisson, negative binomial, zero-inflated, ordered regression, Cox, and Aalen models. The 1.0.0 milestone opened node_cox() to arbitrary baseline hazard functions, which lets continuous time-dependent hazards drive discrete-event simulations. The two most recent releases exist only to keep the package on CRAN through breakage in lme4 and simr.
◆ Where it's heading
The package has been widening what a simulation can represent rather than deepening any one node. Networks arrived in 0.4.0 so individuals could depend on each other, discrete-event simulation in continuous time arrived in 0.5.0 as an alternative to the discrete-time engine, and 1.0.0 connected the two by letting continuous hazards feed the event-driven path. Alongside that, node types keep accumulating for outcome families the framework could not previously generate.
◆ Prediction
Expect the node library to keep expanding into outcome types the discrete-event engine can now support, though the recent releases suggest upstream dependency churn will keep consuming release slots.
