Developed outside the platforms our data source measures, so there is no activity history to score. This says nothing about the project — many unrated projects are actively maintained.

Is Zimbra Collaboration actively maintained?

We cannot measure this one. Zimbra Collaboration is developed outside the platforms our data source collects activity from, and its repository lives at github.com — so there is no commit history or release cadence here to score.

Read that as missing data, not as a warning. Several of the best-maintained projects in this catalogue are unrated for exactly this reason. To judge it, open the repository and look at the date of the most recent commit yourself.

What Zimbra Collaboration actually does

Zimbra Collaboration is a groupware server providing email, calendar management, and collaborative workspace tools accessed via a web interface. It integrates multiple communication features into a single self-hosted platform for organisational use.

Best fit: It is suited for organisations needing an on-premise email and calendar suite with web-based access.

Worth knowing: Activity and release history are currently absent, suggesting potential stagnation or a lack of public repository updates.

Deployment notes

Being built with Java, it typically requires adequate memory allocation and sits behind a reverse proxy to handle TLS termination.
