BigBlueButton vs coturn
A side-by-side editorial comparison of BigBlueButton and coturn — release velocity, themes, recent moves, and the top alternatives to consider.
BigBlueButton vs coturn: at a glance
What is BigBlueButton?
BigBlueButton 4.0 rc.5 drops Etherpad and makes BlockNote the only notes editor.
BigBlueButton 4.0.0-rc.5 removes Etherpad, so upgrading uninstalls bbb-etherpad and bbb-pads and leaves BlockNote as the only shared-notes editor. It also moves Node components to Node.js 24, switches the client to the 1.0 pre-release plugin SDK, and redesigns the poll and quiz panels. It follows two security-only candidates, and the project still recommends 3.0.x for production.
What is coturn?
coturn ships three minor versions in six weeks, packaged as Docker images on three registries.
The tracked feed for coturn, the open-source TURN/STUN server, is Docker image releases: 4.16.0, 4.17.0, 4.17.1, 4.17.2 and 4.18.0 between late July and early September 2026. Each is published to Docker Hub, GitHub Container Registry and Quay.io, and the release notes here point to the upstream changelog without listing changes.

BigBlueButton
5.0MEETINGS
BigBlueButton 4.0 rc.5 drops Etherpad and makes BlockNote the only notes editor.
◆ Current state
BigBlueButton 4.0.0-rc.5 removes Etherpad, so upgrading uninstalls bbb-etherpad and bbb-pads and leaves BlockNote as the only shared-notes editor. It also moves Node components to Node.js 24, switches the client to the 1.0 pre-release plugin SDK, and redesigns the poll and quiz panels. It follows two security-only candidates, and the project still recommends 3.0.x for production.
◆ Where it's heading
The 4.0 cycle is removing legacy components one by one: SIP.js audio went in beta.4, and Etherpad goes now. Between the removals, security-only candidates harden the new LiveKit audio and BlockNote notes surfaces. The plugin SDK reaching a 1.0 pre-release suggests the extension API is being frozen for GA.
◆ Prediction
Expect at least one more candidate to settle the plugin SDK 1.0 change and Etherpad removal before 4.0.0 GA. The pace of security advisories makes the exact timing unclear.
coturn
2.5MEETINGS
coturn ships three minor versions in six weeks, packaged as Docker images on three registries.
◆ Current state
The tracked feed for coturn, the open-source TURN/STUN server, is Docker image releases: 4.16.0, 4.17.0, 4.17.1, 4.17.2 and 4.18.0 between late July and early September 2026. Each is published to Docker Hub, GitHub Container Registry and Quay.io, and the release notes here point to the upstream changelog without listing changes.
◆ Where it's heading
The cadence picked up: three minor versions (4.16, 4.17, 4.18) landed in about six weeks, with two same-day patch images for 4.17. The project keeps container packaging in lockstep with upstream releases, which matters to operators running TURN for WebRTC in containers.
◆ Prediction
A 4.18.x patch image or a 4.19.0 release is the likely next entry, following the observed roughly two-to-four-week rhythm; the feature content is not visible from these entries.
