BigBlueButton vs Mux: 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 Mux?
Mux Robots lands on the Free plan and gains a Directives API for programmatic video workflow control.
Mux is expanding its Robots automation layer through both broader access and deeper control. Robots — which handles automated video processing tasks like thumbnail selection — is now available on the Free plan with 100K units/month. The Directives API, released in July, brought programmatic control over Robots workflows that previously required dashboard interaction. The mobile SDKs gained offline DRM on Android, and analytics gained rendition-level playing time tracking.

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.
Mux
5.0MEETINGSCOMMS
Mux Robots lands on the Free plan and gains a Directives API for programmatic video workflow control.
◆ Current state
Mux is expanding its Robots automation layer through both broader access and deeper control. Robots — which handles automated video processing tasks like thumbnail selection — is now available on the Free plan with 100K units/month. The Directives API, released in July, brought programmatic control over Robots workflows that previously required dashboard interaction. The mobile SDKs gained offline DRM on Android, and analytics gained rendition-level playing time tracking.
◆ Where it's heading
Mux is systematically moving its video intelligence features from premium to broader availability and from dashboard-only to API-first. Robots is emerging as the central abstraction over the video pipeline — the same layer that today handles thumbnails will likely expand to transcoding, captioning, and moderation. The Directives API makes Robots something teams can integrate into CI/CD pipelines or CMS workflows, not just trigger manually.
◆ Prediction
The next Mux move is likely expanding Robots Directives to cover transcoding and captioning workflows, turning Robots into a full programmatic replacement for manual dashboard-driven video processing.
