Group-Office

Group-Office is a PHP-based, self-hosted groupware, CRM, and document-management platform developed by the Dutch company Intermesh since 2003. The open-source Group-Office Community edition is licensed under the AGPL and provides email, calendar, contacts, files, and notes; project management and time tracking are delivered through the commercial Group-Office Professional edition, which also runs on your own server. It integrates the Collabora Online office suite for in-browser document editing.

Our verdict

Last verified Jun 15, 2026

A long-standing, self-hostable Dutch groupware suite (since 2003) where project and time tracking live alongside email, calendar, files, CRM, and Collabora document editing — strong for teams wanting PM inside a wider workspace. Held back because the project-management and time-tracking modules are part of the paid Professional edition, not the free AGPL Community core.
