BigBlueButton vs Nextcloud Talk: at a glance
What is BigBlueButton?
BigBlueButton 4.0 rc.4 is a security-only release as the LiveKit stack hardens.
BigBlueButton 4.0.0-rc.4 contains security fixes only, including a command injection through destination_number, unauthenticated access to a meeting's audio conference and shared notes reachable by non-members. It follows rc.2, also security-only, and rc.3, which focused on LiveKit reconnection and test stability. The project still recommends 3.0.x for production.
What is Nextcloud Talk?
Nextcloud Talk v25 adds classified conversations and an owner role, targeting regulated enterprise deployments.
Nextcloud Talk is on a tight release candidate track for v25, with alpha and two RCs shipping in quick succession. The alpha introduced classified conversations, a new owner role with promotion controls, global message search, and a preservation setting that prevents conversation deletion—enterprise and compliance-grade additions. Maintenance releases for v22 and v23 continue in parallel, with backported security and UI fixes.

BigBlueButton
5.0MEETINGS
BigBlueButton 4.0 rc.4 is a security-only release as the LiveKit stack hardens.
◆ Current state
BigBlueButton 4.0.0-rc.4 contains security fixes only, including a command injection through destination_number, unauthenticated access to a meeting's audio conference and shared notes reachable by non-members. It follows rc.2, also security-only, and rc.3, which focused on LiveKit reconnection and test stability. The project still recommends 3.0.x for production.
◆ Where it's heading
The 4.0 cycle has moved from architecture (LiveKit as the only media path, BlockNote notes, Java 21) to hardening. Two security-only candidates in a month show the new LiveKit audio and notes surfaces are getting close scrutiny before GA.
◆ Prediction
Expect 4.0.0 GA once the release-candidate cadence quiets, likely preceded by at least one more rc. The steady flow of advisories makes the exact timing unclear.
Nextcloud Talk
6.3MEETINGS
Nextcloud Talk v25 adds classified conversations and an owner role, targeting regulated enterprise deployments.
◆ Current state
Nextcloud Talk is on a tight release candidate track for v25, with alpha and two RCs shipping in quick succession. The alpha introduced classified conversations, a new owner role with promotion controls, global message search, and a preservation setting that prevents conversation deletion—enterprise and compliance-grade additions. Maintenance releases for v22 and v23 continue in parallel, with backported security and UI fixes.
◆ Where it's heading
The classified conversations, preservation settings, and call group restrictions in v25 are directly applicable to regulated sectors—healthcare, government, legal—where communication visibility and retention are controlled. Configurable call summary prompts in RC2 add an AI layer to meeting intelligence. Nextcloud Talk is positioning as the self-hosted alternative for organizations that can't route communications through SaaS platforms.
◆ Prediction
v25 stable is likely days away given RC3 is minor fix work. Expect the configurable AI call summaries to expand toward action-item extraction and transcript search in subsequent releases, following patterns from commercial meeting intelligence tools.
