ONLYOFFICE Docs

ONLYOFFICE Docs, the secure, self-hosted alternative to Microsoft Office

Edit, share, and collaborate on documents, spreadsheets, and presentations without the subscription treadmill or vendor lock-in.

Why teams are moving away from Microsoft Office

Microsoft Office is the industry standard but that standard comes with real trade-offs.

For businesses, governments, and developers who want predictable costs and control over their own infrastructure, those trade-offs add up.

AI features (Copilot) sold as a separate paid add-on: around $30/user/month on top of your base plan.
Subscription costs that keep climbing, year after year.
No native app for Linux, only browser-based Office or a Windows VM workaround.
Files and workflows tied to Microsoft's cloud (OneDrive/SharePoint) by default.
Complex licensing tiers that make costs hard to predict.
Limited flexibility for organizations that need full data sovereignty.

True Microsoft Office file compatibility
Built on Office Open XML, the same core format as DOCX, XLSX, and PPTX, so formatting stays intact with no lossy conversion.
Real collaboration without compromise
Real-time and paragraph-locking co-editing. Comments, track changes, and version history. Role-based access control. Secure document sharing.
A real PDF editor, not just a viewer
Go beyond basic tools with a full-featured PDF editing environment.
Full control of your data
Host ONLYOFFICE on your own server or private cloud. Your documents stay where you decide.
Flexible licensing
Choose a subscription or a perpetual on-premise license. Pick the model that fits your budget, not the other way around.
Work with your tools
50+ ready-made connectors, including SharePoint, Nextcloud, ownCloud, Odoo, WordPress, and Confluence.
Work anywhere, including Linux
Native desktop apps for Windows, macOS, and Linux, plus browser and mobile access even offline.
Open and flexible
Customize, extend, and embed ONLYOFFICE into your own apps and workflows.
AI on your terms
Connect OpenAI, Anthropic, DeepSeek, Gemini, or fully local models via Ollama and LM Studio without a mandatory per-seat AI add-on.
