ONLYOFFICE Docs, the actively developed, collaborative alternative to Apache OpenOffice
The same open-source freedom, plus real-time co-editing, mobile apps, and a team that ships security fixes fast.

Why teams look for an OpenOffice alternative
For teams that need collaboration, mobile access, and software that keeps pace with new file formats and AI, those gaps matter.
No real-time collaboration or cloud version - OpenOffice is a desktop-only application
No official mobile apps for Android or iOS
A small volunteer team means fixes can take time: the November 2025 release alone patched seven CVEs across two prior versions
DOCX/XLSX/PPTX formatting can shift, since OpenOffice's OOXML import filters haven't kept pace with newer format changes
No AI features, built-in or otherwise
Long gaps between releases
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.
Actively maintained
Get regular updates and direct enterprise support plans when you need it.
The same open-source freedom
Like OpenOffice, ONLYOFFICE Docs' code is open-source and listed 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.
Native mobile and web apps
Edit documents, sheets, and slides in your browser or on official Android/iOS apps, not just on desktop.
Work with your tools
50+ ready-made connectors, including SharePoint, Odoo, Nextcloud, ownCloud, Confluence, and more.
