Dendrite vs Fonoster
A side-by-side editorial comparison of Dendrite and Fonoster — release velocity, themes, recent moves, and the top alternatives to consider.
Dendrite vs Fonoster: at a glance
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.
What is Fonoster?
Fonoster jumps to v0.33 in a week, rebuilding its SIP and media edge and defaulting to HTTPS.
Fonoster went from v0.22 to v0.33 in the feed within a week. v0.31.0 redesigns Roomr as the SIP and media edge and adds warm transfers, call records with who answered, and a redesigned Calls view with recordings. v0.32.0 makes HTTPS the default with a locally generated CA and removes the CLI's --insecure flag, and v0.33.0 lets callers talk to stream apps and adds Routr telemetry.

◆ 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.
Fonoster
6.3COMMS
Fonoster jumps to v0.33 in a week, rebuilding its SIP and media edge and defaulting to HTTPS.
◆ Current state
Fonoster went from v0.22 to v0.33 in the feed within a week. v0.31.0 redesigns Roomr as the SIP and media edge and adds warm transfers, call records with who answered, and a redesigned Calls view with recordings. v0.32.0 makes HTTPS the default with a locally generated CA and removes the CLI's --insecure flag, and v0.33.0 lets callers talk to stream apps and adds Routr telemetry.
◆ Where it's heading
After parking its diarization work, Fonoster has rebuilt the call path around Roomr and is now making self-hosting secure by default, with a QA catalog gating releases and staged production switches. It reads as a push toward a production-ready voice AI platform rather than a developer preview.
◆ Prediction
Expect further 0.3x releases on transfers, telemetry and self-hosting docs as the new Roomr edge settles.
