Asterisk vs BigBlueButton
A side-by-side editorial comparison of Asterisk and BigBlueButton — release velocity, themes, recent moves, and the top alternatives to consider.
Asterisk vs BigBlueButton: at a glance
What is Asterisk?
Four parallel branches, one fix set — Asterisk's changelog is a backport ledger, not a feature list.
Asterisk maintains mainline 20, 22 and 23 branches alongside a certified track, and lands each fix set across all of them at once. The June 25 batch was a coordinated security release resolving roughly 20 advisories on every branch simultaneously. The August 7 batch opens the next cycle with release candidates carrying identical commit, author and issue counts across 23.5.0, 22.11.0 and 20.21.0.
What is BigBlueButton?
BigBlueButton is polishing the 4.0 beta it already committed to LiveKit, while 3.0 stays the production line.
The 4.0 beta series is in its fifth iteration and the hard architectural decisions are behind it — LiveKit became the default media stack in beta.4 with the legacy SIP.js bridge deleted, BlockNote became the default shared notes engine, and the JVM moved to Java 21. Beta.5 is consolidation: a mobile layout overhaul with paginated webcams and landscape side-by-side camera and presentation, automatic light/dark switching, a dedicated Audio settings tab with push-to-talk, and better BBB-to-LiveKit state reconciliation on reconnect. Packaging gained a bbbctl admin tool and a bbb-coturn package, with bbb-etherpad and bbb-pads now optional. The project still recommends 3.0.x for production.

Asterisk
5.0MEETINGS
Four parallel branches, one fix set — Asterisk's changelog is a backport ledger, not a feature list.
◆ Current state
Asterisk maintains mainline 20, 22 and 23 branches alongside a certified track, and lands each fix set across all of them at once. The June 25 batch was a coordinated security release resolving roughly 20 advisories on every branch simultaneously. The August 7 batch opens the next cycle with release candidates carrying identical commit, author and issue counts across 23.5.0, 22.11.0 and 20.21.0.
◆ Where it's heading
The visible output is backport discipline rather than feature development. Release notes carry counts, tags and advisory IDs but no feature text, so the changelog reads as a stability and security ledger for a mature telephony core. The certified track deliberately lags mainline and picks up a smaller subset of each cycle.
◆ Prediction
The three release candidates should promote to final within the project's usual short RC window, with the certified branch taking the same fixes a cycle later. Nothing in these entries points to feature work in flight.

6.3MEETINGS
BigBlueButton is polishing the 4.0 beta it already committed to LiveKit, while 3.0 stays the production line.
◆ Current state
The 4.0 beta series is in its fifth iteration and the hard architectural decisions are behind it — LiveKit became the default media stack in beta.4 with the legacy SIP.js bridge deleted, BlockNote became the default shared notes engine, and the JVM moved to Java 21. Beta.5 is consolidation: a mobile layout overhaul with paginated webcams and landscape side-by-side camera and presentation, automatic light/dark switching, a dedicated Audio settings tab with push-to-talk, and better BBB-to-LiveKit state reconciliation on reconnect. Packaging gained a bbbctl admin tool and a bbb-coturn package, with bbb-etherpad and bbb-pads now optional. The project still recommends 3.0.x for production.
◆ Where it's heading
The 4.0 line is converging toward a release candidate, and the work has shifted from replacing subsystems to making the new ones survive real conditions — reconnects, phones, and administrator tooling. Making etherpad and pads optional alongside a security advisory that urges API secret rotation points at shrinking the default install's attack surface. The parallel 3.0.x train continues shipping security patches, so the ecosystem is carrying two branches until 4.0 stabilises.
◆ Prediction
Expect beta.6 or a release candidate to focus on the LiveKit reconnection and mobile paths that beta.5 only started, since those are the areas where a self-hosted media migration typically breaks. The optional-package work suggests a slimmer default deployment is being prepared for the 4.0 release.
