BigBlueButton vs Bizzabo: at a glance
What is BigBlueButton?
BigBlueButton 4.0 enters release candidate with LiveKit fully replacing the legacy audio stack.
BigBlueButton is in its final stretch to 4.0 GA, with three release candidates shipping in September 2026. The 4.0 release is a near-complete architectural rebuild: LiveKit has replaced SIP.js and mediasoup as the default media transport, BlockNote replaced the old shared notes engine, and the mobile layout was overhauled. RC2 shipped security fixes for a cross-meeting presentation injection vulnerability, urging immediate admin updates.
What is Bizzabo?
Bizzabo's public feed is an SEO content engine, not a changelog.
Every entry in this window is marketing content — planning guides, listicles, and ROI explainers aimed at enterprise event teams. The recurring argument is that events must prove pipeline impact, and that Bizzabo supplies the attribution and registration infrastructure to do it. No product releases appear in the feed at all.

BigBlueButton 4.0 enters release candidate with LiveKit fully replacing the legacy audio stack.
◆ Current state
BigBlueButton is in its final stretch to 4.0 GA, with three release candidates shipping in September 2026. The 4.0 release is a near-complete architectural rebuild: LiveKit has replaced SIP.js and mediasoup as the default media transport, BlockNote replaced the old shared notes engine, and the mobile layout was overhauled. RC2 shipped security fixes for a cross-meeting presentation injection vulnerability, urging immediate admin updates.
◆ Where it's heading
The LiveKit migration that began in 3.x security patches has culminated in rc.1's 'LiveKit as audio state source' refactor — the legacy audio path is gone. Multi-room sessions with membership-based tokens and automatic token refresh enable scenarios (breakout listen-in, large conferences) that the old bridge couldn't cleanly support. A 4.0 GA release is imminent given the RC cadence.
◆ Prediction
4.0 GA will ship within 2-3 weeks based on the RC pace. Post-GA focus will shift to hardening the LiveKit multi-room session model and expanding BlockNote capabilities (Markdown export landed in beta.4; more collaborative editing features likely next). The successful migration may influence other open-source video conferencing projects still running legacy SFU stacks.
Bizzabo
5.0MEETINGS
Bizzabo's public feed is an SEO content engine, not a changelog.
◆ Current state
Every entry in this window is marketing content — planning guides, listicles, and ROI explainers aimed at enterprise event teams. The recurring argument is that events must prove pipeline impact, and that Bizzabo supplies the attribution and registration infrastructure to do it. No product releases appear in the feed at all.
◆ Where it's heading
The content is converging on measurement: attribution models, ROI reporting, and mobile app adoption framed as data capture. That signals where the company wants to compete — against event platforms that stop at logistics — but it is positioning rather than shipping. Direction cannot be read from this feed with any confidence.
◆ Prediction
Expect more of the same measurement-themed content. Any real product signal would have to come from a channel other than this feed, which carries no release notes.
