BigBlueButton vs LiveKit: 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 LiveKit?
LiveKit keeps hardening its real-time core, this time tightening TURN auth.
LiveKit ships its real-time media server at a steady infra cadence, with v1.13.0 the latest tag. The visible work here is plumbing-level: authentication and connectivity rather than user-facing features.

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.

2.5MEETINGS
LiveKit keeps hardening its real-time core, this time tightening TURN auth.
◆ Current state
LiveKit ships its real-time media server at a steady infra cadence, with v1.13.0 the latest tag. The visible work here is plumbing-level: authentication and connectivity rather than user-facing features.
◆ Where it's heading
The single recent signal points at maintenance of the transport layer, removing legacy TURN auth behavior rather than adding surface. With only one entry in view, the broader arc is hard to read.
◆ Prediction
Expect continued point releases tightening connectivity and auth; the backwards-compatibility removal suggests a cleanup phase ahead of a larger version.
