What is BigBlueButton?

BigBlueButton 4.0 rc.5 drops Etherpad and makes BlockNote the only notes editor.

BigBlueButton 4.0.0-rc.5 removes Etherpad, so upgrading uninstalls bbb-etherpad and bbb-pads and leaves BlockNote as the only shared-notes editor. It also moves Node components to Node.js 24, switches the client to the 1.0 pre-release plugin SDK, and redesigns the poll and quiz panels. It follows two security-only candidates, and the project still recommends 3.0.x for production.

What is Bizzabo?

Bizzabo is selling event software on outcomes: agents for the work, ROI for sponsors.

Bizzabo's feed is mostly buyer-guide content, but two product launches stand out. In October it unveiled AI agents that work across the event lifecycle. In November it made Sponsor ROI generally available, a module that matches sponsors with attendees who fit their target profile and reports back what the sponsorship returned.

BigBlueButton vs Bizzabo: editorial side-by-side

BigBlueButton logo5.0

BigBlueButton 4.0 rc.5 drops Etherpad and makes BlockNote the only notes editor.

◆ Current state

BigBlueButton 4.0.0-rc.5 removes Etherpad, so upgrading uninstalls bbb-etherpad and bbb-pads and leaves BlockNote as the only shared-notes editor. It also moves Node components to Node.js 24, switches the client to the 1.0 pre-release plugin SDK, and redesigns the poll and quiz panels. It follows two security-only candidates, and the project still recommends 3.0.x for production.

◆ Where it's heading

The 4.0 cycle is removing legacy components one by one: SIP.js audio went in beta.4, and Etherpad goes now. Between the removals, security-only candidates harden the new LiveKit audio and BlockNote notes surfaces. The plugin SDK reaching a 1.0 pre-release suggests the extension API is being frozen for GA.

◆ Prediction

Expect at least one more candidate to settle the plugin SDK 1.0 change and Etherpad removal before 4.0.0 GA. The pace of security advisories makes the exact timing unclear.

5.0

Bizzabo is selling event software on outcomes: agents for the work, ROI for sponsors.

◆ Current state

Bizzabo's feed is mostly buyer-guide content, but two product launches stand out. In October it unveiled AI agents that work across the event lifecycle. In November it made Sponsor ROI generally available, a module that matches sponsors with attendees who fit their target profile and reports back what the sponsorship returned.

◆ Where it's heading

The positioning is moving from running events to proving their business value. Both launches aim at the questions event teams get from leadership and sponsors: what did this cost in staff time, and what did it return. The content marketing (portfolio management, enterprise readiness, pipeline-linked webinars) tells the same story.

◆ Prediction

The entries suggest more agent features tied to measurable outcomes, but they don't show which workflow the agents will cover next, so the next step is unclear.
