BigBlueButton vs Bizzabo: at a glance
What is BigBlueButton?
BigBlueButton's 4.0 beta defaults to a Unified layout and ships a WASM audio processor.
BigBlueButton is running two parallel tracks: aggressive maintenance on the 3.0 line (six security-and-improvement releases between January and March, with LiveKit audio stabilization the recurring theme) and a 4.0 beta cycle that just hit beta.3 with substantial UX work. v4.0.0-beta.3 makes the Unified layout the default, adds a WASM-based audio processor on the mic stream, introduces user search, a 3-state presenter lock policy, pinned moderator messages, a viewer 'Request to Become Presenter' flow, and Ubuntu 24.04 support.
What is Bizzabo?
Bizzy AI goes platform-wide as Bizzabo's attendee copilot graduates to every event
Bizzabo is an enterprise event-management platform. Its feed is mostly SEO/education content on sponsorship, lead capture, and platform comparisons, but the most recent entry is a genuine product move: its Bizzy AI attendee copilot is now available for every event, not just select programs.

BigBlueButton's 4.0 beta defaults to a Unified layout and ships a WASM audio processor.
◆ Current state
BigBlueButton is running two parallel tracks: aggressive maintenance on the 3.0 line (six security-and-improvement releases between January and March, with LiveKit audio stabilization the recurring theme) and a 4.0 beta cycle that just hit beta.3 with substantial UX work. v4.0.0-beta.3 makes the Unified layout the default, adds a WASM-based audio processor on the mic stream, introduces user search, a 3-state presenter lock policy, pinned moderator messages, a viewer 'Request to Become Presenter' flow, and Ubuntu 24.04 support.
◆ Where it's heading
BBB is preparing for the 4.0 line as the long-term successor to 3.0. The Unified layout (introduced opt-in in 3.0.19 back in January) is becoming the default; audio infrastructure is being modernized via WASM. The pattern of security patches every two to four weeks on 3.0 signals strong institutional-deployment support discipline. Beta cadence on 4.0 suggests GA is still some months out.
◆ Prediction
Expect a few more 4.0 beta iterations before release candidates, with feature work converging toward GA in Q3 2026. The 3.0 line will continue to receive security-focused maintenance — institutional users (universities, training orgs) tend to lag on majors, so the dual-track will continue past 4.0 GA.

Bizzy AI goes platform-wide as Bizzabo's attendee copilot graduates to every event
◆ Current state
Bizzabo is an enterprise event-management platform. Its feed is mostly SEO/education content on sponsorship, lead capture, and platform comparisons, but the most recent entry is a genuine product move: its Bizzy AI attendee copilot is now available for every event, not just select programs.
◆ Where it's heading
Bizzabo is threading AI through the attendee experience — session recommendations, logistical Q&A, and engagement data — while its content arm pushes the sponsorship-ROI and lead-capture-to-pipeline story to enterprise buyers. The platform is converging on AI-assisted events plus measurable revenue attribution.
◆ Prediction
Expect Bizzy AI to expand from attendee-facing help into organizer-side workflows (analytics, recommendations, sponsor matching), and for the blog to keep tying events to pipeline.
