## What it is
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
