BigBlueButton vs Owncast: 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 Owncast?
Owncast is five years in and still polishing the v0.2 backend before any big features land.
Owncast is deep in a multi-release backend refactor — extracting repositories and services (UserRepository, ConfigRepository, WebhooksRepository, ChatMessageRepository), spec-first API design, modernizing the Go runtime — while shipping incremental improvements around its two distinguishing features: Fediverse integration and self-hosted streaming. Recent releases add translation infrastructure, broader codec support (VA-API new implementation, QuickSync), Fediverse follower cleanup, and operational niceties like favicon customization and required chat auth. The team has explicitly told users that v0.2.x will keep going until the refactor is done.

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.
Owncast
1.7MEETINGS
Owncast is five years in and still polishing the v0.2 backend before any big features land.
◆ Current state
Owncast is deep in a multi-release backend refactor — extracting repositories and services (UserRepository, ConfigRepository, WebhooksRepository, ChatMessageRepository), spec-first API design, modernizing the Go runtime — while shipping incremental improvements around its two distinguishing features: Fediverse integration and self-hosted streaming. Recent releases add translation infrastructure, broader codec support (VA-API new implementation, QuickSync), Fediverse follower cleanup, and operational niceties like favicon customization and required chat auth. The team has explicitly told users that v0.2.x will keep going until the refactor is done.
◆ Where it's heading
The arc is plumbing-first, features-second — and that's by stated design. Activity is steady but slow (five releases over 16 months), and each release is a mix of cleanup, Fediverse fixes, and small QoL items. The Matrix migration of the project's own community chat hints at where the team puts its bets long-term. Until the repository/service refactor lands, expect each release to look much like the last.
◆ Prediction
The next release will be another v0.2.x with more repository extractions, more Fediverse polish (federation shared inbox follow-ups), and additional translation coverage. A v0.3 line — when it appears — is the signal to watch for the 'big features' the team keeps deferring.
