Openfire vs Stalwart: 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 Stalwart?
Stalwart adds full SCIM v2 provisioning and 24-language calendar support as its standards coverage extends further than most commercial mail servers.
Stalwart is maintaining a weekly-or-faster release cadence, with alternating feature releases and dense bug-fix releases. The v0.16.20 release landed full SCIM v2 (Enterprise) including cursor-based pagination and the IPSIE lifecycle profile, conference links in calendar invites, and 24 new calendar interface translations. Below the feature line, the project is steadily closing correctness gaps across JMAP, CalDAV, IMAP, and MTA — many of them edge-case RFC compliance issues.

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.
Stalwart
6.3COMMS
Stalwart adds full SCIM v2 provisioning and 24-language calendar support as its standards coverage extends further than most commercial mail servers.
◆ Current state
Stalwart is maintaining a weekly-or-faster release cadence, with alternating feature releases and dense bug-fix releases. The v0.16.20 release landed full SCIM v2 (Enterprise) including cursor-based pagination and the IPSIE lifecycle profile, conference links in calendar invites, and 24 new calendar interface translations. Below the feature line, the project is steadily closing correctness gaps across JMAP, CalDAV, IMAP, and MTA — many of them edge-case RFC compliance issues.
◆ Where it's heading
Stalwart is building toward parity with commercial enterprise mail servers on identity federation and provisioning (SCIM v2, VAPID for web push, DMARCbis/DKIM2 already landed). The pace of RFC implementation is unusually aggressive for an open-source project; the combination of JMAP, CalDAV, IMAP UIDONLY/UIDBATCHES, and SCIM v2 positions it as a viable self-hosted alternative for organizations that need standards compliance without vendor lock-in.
◆ Prediction
WebAuthn/passkey-based authentication and improved multi-tenant administration tooling are the most likely next capability additions, given the current trajectory toward enterprise identity management.
