BigBlueButton vs WebinarGeek: 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 WebinarGeek?
WebinarGeek's AI now creates webinars from scratch, moving from assistant to production tool
WebinarGeek has been steadily adding an AI Assistant across features over several months — starting as a suggestion tool, evolving into an in-session helper, and now capable of generating a full webinar structure from a prompt. Alongside AI, the platform has added recurring webinar subscriber management, Q&A moderation before publication, UTM tracking, restreaming to external platforms, and expanded Channels functionality.

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.

WebinarGeek's AI now creates webinars from scratch, moving from assistant to production tool
◆ Current state
WebinarGeek has been steadily adding an AI Assistant across features over several months — starting as a suggestion tool, evolving into an in-session helper, and now capable of generating a full webinar structure from a prompt. Alongside AI, the platform has added recurring webinar subscriber management, Q&A moderation before publication, UTM tracking, restreaming to external platforms, and expanded Channels functionality.
◆ Where it's heading
The AI webinar creation feature is the directional step — it positions WebinarGeek not just as a hosting platform but as a production-to-distribution stack. If AI can scaffold the content from a prompt, the competitive moat shifts toward distribution, attendee management, and analytics, where WebinarGeek has been building deliberately. Scheduled AI prompts (added recently) extend this toward automated, recurring content operations.
◆ Prediction
The next logical step is AI-generated follow-up sequences tied to attendee behavior — attendees who asked questions, clicked CTAs, or watched to the end are natural segmentation signals for automated outreach. Closing this loop would make WebinarGeek a full-cycle webinar marketing platform rather than a production and hosting tool.
