WildFly vs Zeebe
A side-by-side editorial comparison of WildFly and Zeebe — release velocity, themes, recent moves, and the top alternatives to consider.
WildFly vs Zeebe: at a glance
What is WildFly?
WildFly's quarterly train is really a stability ladder, and OIDC keeps climbing it
WildFly is four majors into a metronomic release train — 38 through 41 in about eight months — where each cycle pairs a Beta with a Final roughly two weeks later that restates the same feature list. The substantive work splits cleanly in two: Jakarta EE 11 and MicroProfile spec implementations that land first in WildFly Preview, and an explicit stability ladder (preview to community to default) that individual features climb one release at a time. OIDC is the feature getting the most of that attention, with scope attributes, request/request_uri parameters, and logout each promoted across the last three cycles.
What is Zeebe?
Camunda's 8.10 alpha threads a business ID through every layer of the orchestration stack.
This feed is Camunda's monorepo tag stream, so most of what appears in it is machinery rather than software anyone installs: 0.0.0-dryrun-* backport tags and CI hardening dominate by count. The actual content sits in the 8.10.0-alpha4 line, where one theme runs through everything — business IDs as a first-class way to address process instances, wired into the BPMN model, the engine, the protocol, the REST/gRPC/Java clients, FEEL expressions and secondary storage. A separate 8.7 Optimize patch closes two dependency CVEs for the maintenance branch.

WildFly's quarterly train is really a stability ladder, and OIDC keeps climbing it
◆ Current state
WildFly is four majors into a metronomic release train — 38 through 41 in about eight months — where each cycle pairs a Beta with a Final roughly two weeks later that restates the same feature list. The substantive work splits cleanly in two: Jakarta EE 11 and MicroProfile spec implementations that land first in WildFly Preview, and an explicit stability ladder (preview to community to default) that individual features climb one release at a time. OIDC is the feature getting the most of that attention, with scope attributes, request/request_uri parameters, and logout each promoted across the last three cycles.
◆ Where it's heading
The direction is consolidation rather than expansion: features already written are being graduated to supported status instead of new subsystems appearing. In parallel the runtime baseline is moving underneath users — 40.0.1 shipped container images for JDK 25 on UBI 10 and flagged it as the last release carrying JDK 17 images. Expect the EE 11 work now sitting in Preview to graduate into standard WildFly on the same ladder OIDC has been walking.
◆ Prediction
WildFly 42 should ship container images on JDK 21 and JDK 25 only, with the remaining Preview-stability EE 11 integrations promoted toward default.
Zeebe
5.0DEVOPS
Camunda's 8.10 alpha threads a business ID through every layer of the orchestration stack.
◆ Current state
This feed is Camunda's monorepo tag stream, so most of what appears in it is machinery rather than software anyone installs: 0.0.0-dryrun-* backport tags and CI hardening dominate by count. The actual content sits in the 8.10.0-alpha4 line, where one theme runs through everything — business IDs as a first-class way to address process instances, wired into the BPMN model, the engine, the protocol, the REST/gRPC/Java clients, FEEL expressions and secondary storage. A separate 8.7 Optimize patch closes two dependency CVEs for the maintenance branch.
◆ Where it's heading
Business ID is being finished, not started: alpha4 covers deploy-time validation, child propagation, late assignment after job completion, incidents on invalid runtime values and search-API visibility, which is the shape of a feature in its last mile before a stable release. A second, quieter thread is agent-instance lifecycle work — history field renames and cleanup at the end of a process instance — indicating the engine now carries AI agent runs as state it has to retain and then garbage-collect. RBAC is also being consolidated behind a single canonical endpoint-to-permission mapping.
◆ Prediction
The next tags on this line most likely narrow to fixes on the business ID surface rather than opening a new subsystem, since both release candidates in this window carried CI corrections and no feature changes. Whether agent-instance handling becomes a documented capability or stays internal plumbing is not yet visible in these entries.
