BigBlueButton vs Jitsi: 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 Jitsi?
Jitsi rearchitects transcription and adds Document PiP as GSoC 2026 projects ship
Jitsi is modernizing its core infrastructure through Google Summer of Code 2026 contributions: distributed tracing now spans backend components, transcription has been rearchitected after nearly a decade on the Jigasi-based system, and Document Picture-in-Picture is available in browser meetings. The product is absorbing substantive capability work through its open-source contributor pipeline rather than a dedicated product team.

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.

Jitsi rearchitects transcription and adds Document PiP as GSoC 2026 projects ship
◆ Current state
Jitsi is modernizing its core infrastructure through Google Summer of Code 2026 contributions: distributed tracing now spans backend components, transcription has been rearchitected after nearly a decade on the Jigasi-based system, and Document Picture-in-Picture is available in browser meetings. The product is absorbing substantive capability work through its open-source contributor pipeline rather than a dedicated product team.
◆ Where it's heading
The transcription rearchitecture and distributed tracing suggest Jitsi is investing in the backend foundations needed to scale or extend to new use cases — potentially AI-assisted meeting features that require more reliable speech input. Document PiP extends the multi-window collaboration surface. The GSoC model means capabilities arrive in bursts aligned with academic timelines.
◆ Prediction
AI transcription or summarization features are a likely application of the new transcription architecture, given the investment in rebuilding it from scratch and the AI-meeting category trend.
