What is it?

EGroupware is a web-based groupware server written in PHP. It combines webmail, calendar, address book, and project management into one self-hosted collaboration suite that runs in a browser.

The topics on the project point to CalDAV and CardDAV server support, so calendars and contacts can be synced with standard clients. Installation is recommended through Linux distribution packages (DEB/RPM), while Docker is provided for non-Linux systems and unsupported distributions. A development setup is also available through Docker, and it includes a push-server container.

The project's update tooling lets administrators switch between release, bugfix, and master channels using an install-cli.php script, with a setup CLI that reports when a schema update is needed.

Things to know
