Element Call vs Greenlight
A side-by-side editorial comparison of Element Call and Greenlight — release velocity, themes, recent moves, and the top alternatives to consider.
Element Call vs Greenlight: at a glance
What is Element Call?
Element Call starts moving to new LiveKit transports and falls back to remote SFUs when needed.
Element Call ships a release candidate roughly every two to three weeks. v0.28.1-rc.1 adds a breaking change that falls back to publishing media on a remote SFU when possible, supports migrating to new LiveKit transport types and endpoints, and fixes room v12 power-level compatibility. It also brings in a MatrixRTC SDK and patches several dependency security advisories. The previous rc added a quick audio menu and redacted analytics IDs from rageshakes.
What is Greenlight?
Greenlight 3.9 makes URL_HOST mandatory, forcing admin action on every self-hosted deployment.
Greenlight, the BigBlueButton web frontend, is in a security-maintenance phase. The 3.8.x series was dominated by gem updates and language patches; 3.9.0 introduces multiple undisclosed security fixes alongside a breaking change that requires URL_HOST to be set in .env or the application will refuse to start. A follow-up hotfix landed hours later to address a startup crash introduced in the release.

Element Call
5.0MEETINGS
Element Call starts moving to new LiveKit transports and falls back to remote SFUs when needed.
◆ Current state
Element Call ships a release candidate roughly every two to three weeks. v0.28.1-rc.1 adds a breaking change that falls back to publishing media on a remote SFU when possible, supports migrating to new LiveKit transport types and endpoints, and fixes room v12 power-level compatibility. It also brings in a MatrixRTC SDK and patches several dependency security advisories. The previous rc added a quick audio menu and redacted analytics IDs from rageshakes.
◆ Where it's heading
With the MatrixRTC protocol cutover finished in August, the team is now working on the media transport layer itself: how calls find and publish to SFUs and how LiveKit endpoints change underneath them. Packaging the RTC logic as an SDK suggests it is meant to be reused beyond the Element Call app.
◆ Prediction
Expect a 0.28.1 final and follow-ups to the LiveKit transport migration; whether the MatrixRTC SDK gets its own release isn't clear from the entries.
Greenlight
5.0MEETINGS
Greenlight 3.9 makes URL_HOST mandatory, forcing admin action on every self-hosted deployment.
◆ Current state
Greenlight, the BigBlueButton web frontend, is in a security-maintenance phase. The 3.8.x series was dominated by gem updates and language patches; 3.9.0 introduces multiple undisclosed security fixes alongside a breaking change that requires URL_HOST to be set in .env or the application will refuse to start. A follow-up hotfix landed hours later to address a startup crash introduced in the release.
◆ Where it's heading
Greenlight's release cadence is maintenance-driven: security response and dependency updates rather than feature work. The 3.9.0 breaking change is the project tightening deployment requirements, likely in response to misconfiguration risks identified in security audits. The rapid hotfix points to limited pre-release testing capacity on the project.
◆ Prediction
The undisclosed 3.9.0 security fixes will be disclosed within weeks and likely explain the URL_HOST mandate — deployments without it were probably vulnerable to host header injection or similar configuration-dependent attacks.
