BigBlueButton vs Fourwaves
A side-by-side editorial comparison of BigBlueButton and Fourwaves — release velocity, themes, recent moves, and the top alternatives to consider.
BigBlueButton vs Fourwaves: at a glance
What is BigBlueButton?
BigBlueButton is polishing the 4.0 beta it already committed to LiveKit, while 3.0 stays the production line.
The 4.0 beta series is in its fifth iteration and the hard architectural decisions are behind it — LiveKit became the default media stack in beta.4 with the legacy SIP.js bridge deleted, BlockNote became the default shared notes engine, and the JVM moved to Java 21. Beta.5 is consolidation: a mobile layout overhaul with paginated webcams and landscape side-by-side camera and presentation, automatic light/dark switching, a dedicated Audio settings tab with push-to-talk, and better BBB-to-LiveKit state reconciliation on reconnect. Packaging gained a bbbctl admin tool and a bbb-coturn package, with bbb-etherpad and bbb-pads now optional. The project still recommends 3.0.x for production.
What is Fourwaves?
Fourwaves is quietly building out the payments layer under its conference admin tools.
Fourwaves publishes a near-daily, one-line changelog covering small changes to the conference organiser's admin surface. The August window is dominated by payments and money administration: transaction filtering by organisation and by payment gateway, the Free plan surfaced in the upgrade checkout, and now Authorize.net added as a supported processor. Around that sits a steady thread of attendee-facing clarity work — a sidebar showing existing form entries, Tracks usable as an email variable — and routine fixes.

BigBlueButton
6.3MEETINGS
BigBlueButton is polishing the 4.0 beta it already committed to LiveKit, while 3.0 stays the production line.
◆ Current state
The 4.0 beta series is in its fifth iteration and the hard architectural decisions are behind it — LiveKit became the default media stack in beta.4 with the legacy SIP.js bridge deleted, BlockNote became the default shared notes engine, and the JVM moved to Java 21. Beta.5 is consolidation: a mobile layout overhaul with paginated webcams and landscape side-by-side camera and presentation, automatic light/dark switching, a dedicated Audio settings tab with push-to-talk, and better BBB-to-LiveKit state reconciliation on reconnect. Packaging gained a bbbctl admin tool and a bbb-coturn package, with bbb-etherpad and bbb-pads now optional. The project still recommends 3.0.x for production.
◆ Where it's heading
The 4.0 line is converging toward a release candidate, and the work has shifted from replacing subsystems to making the new ones survive real conditions — reconnects, phones, and administrator tooling. Making etherpad and pads optional alongside a security advisory that urges API secret rotation points at shrinking the default install's attack surface. The parallel 3.0.x train continues shipping security patches, so the ecosystem is carrying two branches until 4.0 stabilises.
◆ Prediction
Expect beta.6 or a release candidate to focus on the LiveKit reconnection and mobile paths that beta.5 only started, since those are the areas where a self-hosted media migration typically breaks. The optional-package work suggests a slimmer default deployment is being prepared for the 4.0 release.
Fourwaves
5.0MEETINGS
Fourwaves is quietly building out the payments layer under its conference admin tools.
◆ Current state
Fourwaves publishes a near-daily, one-line changelog covering small changes to the conference organiser's admin surface. The August window is dominated by payments and money administration: transaction filtering by organisation and by payment gateway, the Free plan surfaced in the upgrade checkout, and now Authorize.net added as a supported processor. Around that sits a steady thread of attendee-facing clarity work — a sidebar showing existing form entries, Tracks usable as an email variable — and routine fixes.
◆ Where it's heading
The work is aimed at multi-event organisations rather than single-conference organisers; transaction filtering and a second payment processor only matter if you run several events through shared gateways. Adding Authorize.net alongside the existing gateway support turns payments from a fixed part of the platform into something an organisation can choose, which is the prerequisite for selling to institutions that already have a processor relationship. Individually each change is minor; together they describe a platform being made to hold more events per customer.
◆ Prediction
Expect the payments thread to continue — further gateway options or per-organisation payment configuration are the natural next step now that transactions can be filtered by gateway. The date-stamped daily format suggests the cadence holds regardless of the size of what ships.
