Group-Office review
A broad open-source workspace for teams that need files alongside business tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Group-Office is an open-source groupware and CRM platform for teams that need document sharing alongside email, calendars, contacts, projects, tasks and support tickets. It suits small teams looking for free office collaboration tools, especially those that value self-hosting or want a hosted service in the Netherlands. File sharing, WebDAV access, collaborative document editing and device synchronization give it a practical document-focused foundation within a wider business workspace.
The plan structure covers both free and paid routes. Community is a €0 one-time open-source download with unlimited users and includes email, calendars, files, tasks, address books and device synchronization. Professional costs €439 as a one-time perpetual license and adds support tickets, time tracking, projects, newsletters and Kanban. Professional updates cost €219 per year for updates to Professional features. Online costs €12 per month and includes hosted service, daily backup, email, calendars, files, notes, tasks, address books, newsletters, time tracking and projects. A 30-day free trial is also available.
Its ecosystem supports OnlyOffice, Collabora Online, Office 365, Rocket.Chat, IMAP, Microsoft ActiveSync, CalDAV, CardDAV and WebDAV. Group-Office runs on web, Windows, macOS, iOS and Android, with a self-hosted option for teams that want deployment control. Two-factor authentication and encryption are included among the listed features, while custom modules can be created through GroupOffice Studio. Choose it when collaboration, contacts, email and files belong in one system; choose a more specialized document management product when advanced DMS controls are the primary requirement.
