Openfire vs VerneMQ
A side-by-side editorial comparison of Openfire and VerneMQ — release velocity, themes, recent moves, and the top alternatives to consider.
Openfire vs VerneMQ: at a glance
What is Openfire?
Openfire keeps its XMPP server current without changing what it is.
Openfire ships a maintenance release every one to two months, each a mix of dependency upgrades, MUC and pubsub correctness fixes, and occasional security hardening. 5.1.2 follows that shape exactly: Jetty, log4j2, and the PostgreSQL driver moved forward, three inapplicable Tomcat CVEs suppressed, and a set of MUC self-ping errors corrected to return the right XMPP error types. The last release with real feature content was 5.1.0 in June, which added channel binding and an admin console for failed server-to-server connections.
What is VerneMQ?
VerneMQ's 2.2.0 collects a year of cluster and connection fixes into one release.
VerneMQ ships infrequently — the six most recent releases span February 2025 to August 2026 — and 2.2.0 on 9 August gathers roughly a year of accumulated work. Its contents are broker internals: a socket-accounting fix for rapid connect/disconnect churn, MQTT v5 property handling in the Lua auth cache, ETS-mirrored event subscriptions in the SWC metadata store, parallelised inter-node readiness checks, and anonymous-override extended to WebSocket listeners. The 2.1.3 release candidate from April was folded in and the version renumbered.
Openfire vs VerneMQ: editorial side-by-side
Openfire
2.5COMMS
Openfire keeps its XMPP server current without changing what it is.
◆ Current state
Openfire ships a maintenance release every one to two months, each a mix of dependency upgrades, MUC and pubsub correctness fixes, and occasional security hardening. 5.1.2 follows that shape exactly: Jetty, log4j2, and the PostgreSQL driver moved forward, three inapplicable Tomcat CVEs suppressed, and a set of MUC self-ping errors corrected to return the right XMPP error types. The last release with real feature content was 5.1.0 in June, which added channel binding and an admin console for failed server-to-server connections.
◆ Where it's heading
The project's direction is protocol conformance and operational currency rather than new capability. Recent cycles have gone into XEP compliance details - self-ping error semantics, XEP-0398 presence handling, base64 whitespace tolerance - and into keeping the dependency tree clean enough to pass a scanner. That is a reasonable posture for infrastructure a decade into deployment, and nothing in the last six releases suggests a change of scope.
◆ Prediction
Expect the same cadence: another patch in four to eight weeks carrying library bumps and MUC or pubsub conformance fixes, with anything larger held for a 5.2 line.
VerneMQ
2.5COMMS
VerneMQ's 2.2.0 collects a year of cluster and connection fixes into one release.
◆ Current state
VerneMQ ships infrequently — the six most recent releases span February 2025 to August 2026 — and 2.2.0 on 9 August gathers roughly a year of accumulated work. Its contents are broker internals: a socket-accounting fix for rapid connect/disconnect churn, MQTT v5 property handling in the Lua auth cache, ETS-mirrored event subscriptions in the SWC metadata store, parallelised inter-node readiness checks, and anonymous-override extended to WebSocket listeners. The 2.1.3 release candidate from April was folded in and the version renumbered.
◆ Where it's heading
Work concentrates on cluster behaviour and connection churn — the failure modes large MQTT fleets actually hit — rather than on protocol surface. Defaults are being revisited alongside the fixes: the retain-expiry check is now off by default and SWC initial sync is set to off, both choices that favour predictable behaviour on busy clusters over automatic housekeeping. Development stays maintainer-paced, with dependency bumps making up a visible share of each changelog, and the commercial EULA on binary packages continues to sit alongside the open source.
◆ Prediction
The next release is most likely another long-cycle collection of cluster and listener fixes rather than a feature line. Nothing in these entries points to a 3.0 direction.
