BigBlueButton vs BoxCast: 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 BoxCast?
BoxCast teaches churches to stream better with gear they already own — and ships nothing here.
BoxCast's feed is production education for the church and ministry market, not a changelog. The recent run covers improving a stream without new equipment, which streaming analytics are worth tracking, remote audio mixing, and what a full cache means on an encoder. It is written for volunteer-staffed AV teams, and the technical posts go deep enough to be genuinely useful.

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.
BoxCast
5.0MEETINGS
BoxCast teaches churches to stream better with gear they already own — and ships nothing here.
◆ Current state
BoxCast's feed is production education for the church and ministry market, not a changelog. The recent run covers improving a stream without new equipment, which streaming analytics are worth tracking, remote audio mixing, and what a full cache means on an encoder. It is written for volunteer-staffed AV teams, and the technical posts go deep enough to be genuinely useful.
◆ Where it's heading
The emphasis is shifting toward getting more out of existing hardware — remote mixing without a second board, better output without a new camera — which speaks to budget-constrained buyers rather than upgrade cycles. Analytics is emerging as a second thread, framed around hybrid attendance rather than viewer counts. Posting is roughly weekly and none of it dates a platform change.
◆ Prediction
Expect continued volunteer-enablement and audio content, with analytics guidance growing as churches try to read hybrid attendance. Nothing here indicates what BoxCast is changing in the product itself.
