BigBlueButton vs Webex: 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 Webex?

The crawled feed is the Webex blog, and it carries positioning, customer stories and analyst recognition rather than a changelog. The current window is conference marketing ahead of WebexOne 2026 and a device how-to. Actual product news appears only when a blog post happens to describe it, as with the AI Agent reaching on-premises Cisco CCE 15.

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.

◆ Current state
The crawled feed is the Webex blog, and it carries positioning, customer stories and analyst recognition rather than a changelog. The current window is conference marketing ahead of WebexOne 2026 and a device how-to. Actual product news appears only when a blog post happens to describe it, as with the AI Agent reaching on-premises Cisco CCE 15.
◆ Where it's heading
The consistent theme is AI applied to contact-centre work — containment rates, self-service, agent efficiency — with customer stories used as the proof. The one genuinely differentiated thread is bringing that AI to on-premises deployments rather than requiring a move to cloud, which speaks to Cisco's installed base. Bodies here are truncated at source, so depth has to be confirmed elsewhere.
◆ Prediction
Expect WebexOne announcements to dominate the next stretch of this feed, with the AI Agent and contact-centre line the most likely subjects. Release-level detail will not come from this source.
