BigBlueButton vs Restream: 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 Restream?
Restream deepening X integration and adding Slack as a live streaming destination
Restream is shipping steady improvements across its live streaming studio: flexible element positioning, live-edit mode for scene changes without going off-air, new destination platforms (Rumble for clips, Slack for webinars), and deeper X integration with chat replies and viewer analytics. The release cadence is approximately one functional update per week, covering both the creator streaming workflow and an emerging enterprise broadcast use case.

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.

Restream deepening X integration and adding Slack as a live streaming destination
◆ Current state
Restream is shipping steady improvements across its live streaming studio: flexible element positioning, live-edit mode for scene changes without going off-air, new destination platforms (Rumble for clips, Slack for webinars), and deeper X integration with chat replies and viewer analytics. The release cadence is approximately one functional update per week, covering both the creator streaming workflow and an emerging enterprise broadcast use case.
◆ Where it's heading
Restream is expanding in two directions simultaneously: more destinations to stream to (X, Slack, Rumble) and a more capable real-time production studio (live scene editing, free-form element positioning). The Slack townhall and webinar capability is the more directional move — it suggests Restream is reaching beyond the creator and streamer audience into enterprise internal communications. If Slack broadcast gains adoption, it repositions the product from streaming tool to all-hands broadcast platform.
◆ Prediction
Expect continued expansion of X analytics capabilities and additional enterprise-relevant destinations — Microsoft Teams or Zoom webinar integration would be a natural next step following the Slack townhall direction.
