Casdoor vs Dragonfly
A side-by-side editorial comparison of Casdoor and Dragonfly — release velocity, themes, recent moves, and the top alternatives to consider.
Casdoor vs Dragonfly: at a glance
What is Casdoor?
casdoor ships several times a day, mostly tightening organization boundaries.
Casdoor is an open-source identity and access management platform releasing several times a day under semantic-release, often a single commit per version. The recent window is dominated by multi-tenant boundary work: cross-org webhook restrictions, organization checks on add APIs, and organization-prefixed DingTalk group IDs. Admin UI correctness fixes fill the rest.
What is Dragonfly?
Dragonfly is spending its releases on correctness debt, not features.
The last two months are almost entirely correctness work: a pub/sub ordering bug that silently discarded queued messages on unsubscribe, a multi-key PFCOUNT that read sixteen wrong registers, an uninitialized pointer in the sparse HyperLogLog promote path, and now cluster FLUSHSLOTS that was not journaled inside its own flush transaction. The one structural move is the resync of the forked hyperloglog.c against valkey upstream, which cut divergence from 2,139 lines to 767 and pulled in a CVE fix plus AVX2 and NEON merge kernels. New user-facing options are rare; the list compression tuning flags are the exception.

◆ Current state
Casdoor is an open-source identity and access management platform releasing several times a day under semantic-release, often a single commit per version. The recent window is dominated by multi-tenant boundary work: cross-org webhook restrictions, organization checks on add APIs, and organization-prefixed DingTalk group IDs. Admin UI correctness fixes fill the rest.
◆ Where it's heading
Two threads dominate. The first is tenant isolation, a run of consecutive releases restricting what one organization can reach in another, which reads as closing a class of gaps systematically rather than one report at a time. The second is admin UI correctness: disabling persisted-entity actions on add pages, showing display names in role and permission editors, reloading records after creation. The DingTalk integration draws incremental attention across both.
◆ Prediction
The org-boundary fixes have landed in consecutive releases and look unfinished, so more of the same is likely; nothing in the entries points to a new authentication protocol or a larger feature.

5.0INFRA · APIS
Dragonfly is spending its releases on correctness debt, not features.
◆ Current state
The last two months are almost entirely correctness work: a pub/sub ordering bug that silently discarded queued messages on unsubscribe, a multi-key PFCOUNT that read sixteen wrong registers, an uninitialized pointer in the sparse HyperLogLog promote path, and now cluster FLUSHSLOTS that was not journaled inside its own flush transaction. The one structural move is the resync of the forked hyperloglog.c against valkey upstream, which cut divergence from 2,139 lines to 767 and pulled in a CVE fix plus AVX2 and NEON merge kernels. New user-facing options are rare; the list compression tuning flags are the exception.
◆ Where it's heading
Two threads run in parallel. One reduces the cost of carrying a Redis fork by re-syncing individual files against valkey and leaving provenance notes so the next sync is cheap. The other hardens the V2 IO loop while the V1 path still takes the fixes — several commits explicitly defer the V2 half of a fix to a later change, so the two loops are not at parity. Cluster correctness around slot migration and journaling is the newest front.
◆ Prediction
The deferred V2 IO-loop fixes are the obvious next commits, and more forked Redis files are likely to get the same upstream resync treatment now that the pattern and its accounting are established.
