Nextcloud Talk vs BigBlueButton: at a glance
What is Nextcloud Talk?
Two parallel Talk lines: a 24.0 feature push in RC, a 22.0 stable stream in maintenance.
Nextcloud Talk (the spreed app) is the self-hosted voice, video, and chat layer of Nextcloud. The feed shows two branches moving at once: the 22.0 stable line churning out backport-heavy patch releases, and the 24.0 line working through release candidates. Recent 22.0 work is mostly call-reliability fixes (iOS audio mixing, camera constraints, media-device handling) and dependency bumps.
What is BigBlueButton?
BigBlueButton's 4.0 beta swaps out its own media stack — LiveKit is now the default, SIP.js is gone.
Two lines run in parallel. The stable 3.0 branch gets maintenance iterations every few weeks — security fixes, breakout-room and screenshare repairs, audio fixes against LiveKit — while 4.0 betas carry the structural work. The latest beta makes LiveKit the default media stack and deletes the legacy SIP.js audio bridge, replaces the shared notes engine with BlockNote, and moves the JVM services to Java 21. The layout system was rebuilt one beta earlier, with the Unified layout promoted to default.

Nextcloud Talk
5.0MEETINGS
Two parallel Talk lines: a 24.0 feature push in RC, a 22.0 stable stream in maintenance.
◆ Current state
Nextcloud Talk (the spreed app) is the self-hosted voice, video, and chat layer of Nextcloud. The feed shows two branches moving at once: the 22.0 stable line churning out backport-heavy patch releases, and the 24.0 line working through release candidates. Recent 22.0 work is mostly call-reliability fixes (iOS audio mixing, camera constraints, media-device handling) and dependency bumps.
◆ Where it's heading
The substantive feature bets landed earlier in the 24.0 beta — permanent call rooms, advanced noise suppression, calls from the avatar menu, conversation tagging — and the current releases are stabilizing them toward a stable cut. The 22.0 stream will keep receiving call and federation hardening in parallel. Momentum is on hardening real-time calling and SIP/federation edge cases rather than new surface.
◆ Prediction
The 24.0 line looks headed for a stable release once the RC call and chat fixes settle, with the 22.0 stream continuing to receive backported reliability patches.
BigBlueButton
3.8MEETINGS
BigBlueButton's 4.0 beta swaps out its own media stack — LiveKit is now the default, SIP.js is gone.
◆ Current state
Two lines run in parallel. The stable 3.0 branch gets maintenance iterations every few weeks — security fixes, breakout-room and screenshare repairs, audio fixes against LiveKit — while 4.0 betas carry the structural work. The latest beta makes LiveKit the default media stack and deletes the legacy SIP.js audio bridge, replaces the shared notes engine with BlockNote, and moves the JVM services to Java 21. The layout system was rebuilt one beta earlier, with the Unified layout promoted to default.
◆ Where it's heading
This is a multi-year replacement of the plumbing under a conferencing platform, done in public and in order: introduce LiveKit alongside the old bridge, fix audio against it across 3.0 point releases, then cut the old path out in a 4.0 beta. The same pattern shows in the client — the Unified layout arrived opt-in in 3.0.19 and became the default in beta.3. Around the core swap, the surface is being tidied: app gallery search and pinning, notification redesign, a request-to-present flow, configurable plugin buttons.
◆ Prediction
With the legacy audio bridge removed and Java 21 in place, expect the remaining 4.0 betas to be stabilization rather than new subsystems, and expect self-hosters to hit LiveKit deployment issues that generate a run of point releases after 4.0 lands.
