Openfire vs Dendrite: at a glance
What is Openfire?
Openfire's 5.1 line pairs XMPP channel binding with a steady cleanup of its own crypto
Six releases across the 5.0 and 5.1 lines, each a long list of numbered improvements and bug fixes. The 5.1.0 release is the substantive one: support for channel binding, an admin console page for reviewing failed server-to-server connection attempts, visible S2S ports, and removal of a hardcoded initialization vector and a weak SHA-1-derived Blowfish key. The rest is multi-user chat correctness, pubsub behaviour and dependency currency.
What is Dendrite?
A forked, relicensed Dendrite spent its first year catching up on Matrix protocol and security debt
The window opens with the first release after forking from matrix-org/dendrite under AGPLv3, which fixed long-standing state-reset bugs and added I2P and Onion listening. What follows is a security release closing a server-side request forgery vulnerability, then a release adding room version 12 support and two MSC implementations, and finally two quick patches for unresponsiveness, v12 room joins and malformed PDUs blocking whole transactions.

◆ Current state
Six releases across the 5.0 and 5.1 lines, each a long list of numbered improvements and bug fixes. The 5.1.0 release is the substantive one: support for channel binding, an admin console page for reviewing failed server-to-server connection attempts, visible S2S ports, and removal of a hardcoded initialization vector and a weak SHA-1-derived Blowfish key. The rest is multi-user chat correctness, pubsub behaviour and dependency currency.
◆ Where it's heading
Two consistent threads run through the window: replacing the older cryptographic shortcuts still sitting in the codebase, and making federation failures diagnosable rather than silent. Multi-user chat and pubsub keep generating the highest volume of fixes, which is a fair map of where a working XMPP server actually spends its time.
◆ Prediction
Expect the 5.1 line to continue with MUC and pubsub fixes plus further dependency upgrades, with any remaining legacy crypto paths the most likely target for the next round of hardening.

◆ Current state
The window opens with the first release after forking from matrix-org/dendrite under AGPLv3, which fixed long-standing state-reset bugs and added I2P and Onion listening. What follows is a security release closing a server-side request forgery vulnerability, then a release adding room version 12 support and two MSC implementations, and finally two quick patches for unresponsiveness, v12 room joins and malformed PDUs blocking whole transactions.
◆ Where it's heading
This is a fork proving it can carry a homeserver. The order is telling: license and state correctness first, then a CVE, then protocol currency with room version 12, then the operational bugs that surface once people actually run it. Several fixes carry outside contributor credits, which is the fork's clearest sign of life.
◆ Prediction
Expect continued protocol catch-up on newer MSCs and room versions plus operational fixes, since federation compatibility is the constraint that sets this project's agenda.
