BigBlueButton vs webinar.net: 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 webinar.net?
webinar.net bets on two niches: AI-citation webinars and white-glove investor relations.
The product is positioning into two distinct verticals simultaneously: investor relations (branded earnings-call experiences for CFOs and IR teams) and generative-engine-optimization (positioning webinar content as AI-search citation sources). Both lean hard on premium, high-stakes use cases rather than mass-market webinar tooling.

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.
webinar.net
0.0MEETINGS
webinar.net bets on two niches: AI-citation webinars and white-glove investor relations.
◆ Current state
The product is positioning into two distinct verticals simultaneously: investor relations (branded earnings-call experiences for CFOs and IR teams) and generative-engine-optimization (positioning webinar content as AI-search citation sources). Both lean hard on premium, high-stakes use cases rather than mass-market webinar tooling.
◆ Where it's heading
The IR positioning is mature and explicit — direct shots at 'grey box' competitor tooling. The GEO/AEO bet is newer and more speculative, framing webinars as a way to be cited by AI search engines rather than summarized away. The January commentary on Cvent's ON24 acquisition shows webinar.net opportunistically positioning itself as the independent alternative as the category consolidates.
◆ Prediction
Expect continued IR-vertical content as earnings seasons land and more concrete GEO/AEO capability claims (structured metadata, transcript-cited content surfaces). The next signal worth watching is whether the GEO positioning gets a real product feature attached or stays as a content theme.
