ONLYOFFICE Docs, the collaborative, MS Office-compatible alternative to LibreOffice
All the openness and freedom you expect, plus real-time co-editing, native mobile apps, and enterprise support built in.
Why teams look for a LibreOffice alternative
LibreOffice is free, open-source, and a solid desktop suite but a few practical gaps send teams looking elsewhere.
For teams that need dependable collaboration, mobile access, and a vendor to call when something breaks, those gaps matter.
No real-time co-editing out of the box - collaborative editing requires setting up a separate server like Collabora Online.
No direct vendor support - you're routed to third-party certified partners.
AI writing tools are still experimental and extension-dependent, not a stable built-in feature.
DOCX/XLSX/PPTX formatting can shift, since LibreOffice is built around the ODF format first.
No official, fully-featured mobile apps for Android or iOS.
Interface can feel dated next to modern cloud-native editors.
What you get with ONLYOFFICE
Highest Microsoft Office compatibility
Built around Office Open XML from the ground up, so DOCX, XLSX, and PPTX files keep their formatting.
Real-time collaboration, built in
Character- and paragraph-level co-editing, comments, and version history work out of the box.
A full-featured PDF editor
Edit, fill, and e-sign PDF forms directly, not just basic markup through a drawing tool.
Native mobile and web apps
Edit documents, sheets, and slides in your browser or on official Android/iOS apps, not just on desktop.
The same open-source freedom
Like LibreOffice, ONLYOFFICE Docs' code is open-source and free to self-host on GitHub. You don't have to trade openness for more features.
AI on your terms, ready today
Stable, built-in AI: connect OpenAI, Anthropic, DeepSeek, Gemini, or local models like Ollama - no beta extension required.
Support when you need it
Direct enterprise support plans, instead of hunting for a certified third-party partner.
Work with your tools
50+ ready-made connectors, including SharePoint, Odoo, Nextcloud, ownCloud, Confluence, and more.
