ONLYOFFICE Groups (formerly Community Server) is a free, open-source self-hosted collaboration platform combining document management, project management, CRM, and mail aggregation in one web-based hub. It is written in C# and distributed under the Apache 2.0 license, typically deployed alongside ONLYOFFICE Docs for online document editing.

Use cases

• self-host a document management system for my team
• manage projects with tasks, milestones and Gantt charts
• track customers and invoices with an open-source CRM
• aggregate company email on my own server
• share and co-edit office documents privately
• replace Google Workspace with an on-premises collaboration suite

When to choose

• you want a single self-hosted hub for documents, projects, CRM, and mail
• you need on-premises deployment for data privacy or compliance (GDPR/HIPAA)
• you already use or plan to use ONLYOFFICE Docs editors
• you want an open-source alternative to proprietary office collaboration suites

When to avoid

• you only need a standalone office suite without collaboration modules - ONLYOFFICE Docs alone may suffice
• you need a lightweight tool - the platform is a heavy multi-service deployment
• you require deep customization beyond the provided API and plugin system
• your team is small and a simple file-sharing tool would be enough
