BigBlueButton vs Microsoft Teams: 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 Microsoft Teams?
Microsoft Teams adds automated trust scoring for apps and agents in the admin center.
The standout Teams release in the recent window is the Organization Trust Score, which automates evaluation of every app and agent against admin-defined security, privacy, and compliance requirements. Adjacent to that, a new Teams Admin Center dashboard tracks voice and face profile enrollment metrics that feed AI-enhanced meeting experiences. Most other recent entries in the feed are Microsoft Learn and documentation page scrapes rather than Teams shipments.

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.
Microsoft Teams
3.8MEETINGSCOMMS
Microsoft Teams adds automated trust scoring for apps and agents in the admin center.
◆ Current state
The standout Teams release in the recent window is the Organization Trust Score, which automates evaluation of every app and agent against admin-defined security, privacy, and compliance requirements. Adjacent to that, a new Teams Admin Center dashboard tracks voice and face profile enrollment metrics that feed AI-enhanced meeting experiences. Most other recent entries in the feed are Microsoft Learn and documentation page scrapes rather than Teams shipments.
◆ Where it's heading
Teams is hardening governance for the agent and app ecosystem before pushing more agentic features into the meetings and chat surface. The pairing — automated trust scoring on the policy side, biometric enrollment visibility on the AI-meeting side — signals Microsoft's posture: AI-driven Teams capabilities will keep arriving, but admin controls land first to keep enterprise tenants comfortable saying yes.
◆ Prediction
Expect deeper extensions of Trust Score (live re-evaluation on app updates, integration with Microsoft Defender for Cloud Apps) and more biometric-driven meeting capabilities like personalized noise suppression and speaker-aware transcription tied to enrolled profiles.
