BigBlueButton vs Wowza: at a glance
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.
What is Wowza?
Wowza's feed is a marketing blog, and right now it is all pre-selling video AI.
This source is the Wowza blog, not a changelog: the recent window is explainers, thought-leadership essays, and customer stories, with no dated release notes in the top entries. The one genuine release visible anywhere in the feed — Streaming Engine 4.11, which adds WHIP and WHEP signaling, full ICE connectivity checks, and configurable STUN and TURN servers — sits several entries down and is echoed second-hand in the use-case posts above it. Everything more recent is about the Video Intelligence Framework, described as a layer that pulls frames off live streams, runs them through AI models, and emits metadata, overlays, and alerts.

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.

5.0MEETINGS
Wowza's feed is a marketing blog, and right now it is all pre-selling video AI.
◆ Current state
This source is the Wowza blog, not a changelog: the recent window is explainers, thought-leadership essays, and customer stories, with no dated release notes in the top entries. The one genuine release visible anywhere in the feed — Streaming Engine 4.11, which adds WHIP and WHEP signaling, full ICE connectivity checks, and configurable STUN and TURN servers — sits several entries down and is echoed second-hand in the use-case posts above it. Everything more recent is about the Video Intelligence Framework, described as a layer that pulls frames off live streams, runs them through AI models, and emits metadata, overlays, and alerts.
◆ Where it's heading
Wowza is repositioning from a streaming server toward an inference pipeline for video nobody watches — substation cameras, traffic feeds, campus security. The essay cadence around VIF, custom model training, and content authenticity is the argument being built before the products arrive, aimed at operational buyers rather than broadcasters. The underlying engineering thread is more conventional: modernizing WebRTC in Streaming Engine so sub-second delivery works from standard browsers without an SDK. Because this feed tracks publishing rather than shipping, the velocity score here reflects blog cadence, not product activity.
◆ Prediction
The concentration of VIF material points to packaging or pricing news for the framework, but this source will only show it as another blog post. The useful fix is on our side: point the crawler at the Wowza release notes so Streaming Engine versions stop arriving as marketing echoes.
