About ONLYOFFICE

ONLYOFFICE makes document, spreadsheet, presentation and PDF editors that look and behave a lot like Microsoft Office and use .docx, .xlsx and .pptx as their native formats, which gives it better Office compatibility than most alternatives. It comes in several forms: free Desktop Editors for Windows, macOS and Linux; mobile apps; ONLYOFFICE Docs, a server you can self-host and plug into Nextcloud, ownCloud, Seafile, SharePoint and other platforms for real-time co-editing; and DocSpace, a hosted collaboration space with rooms. The core of Docs is open source under AGPLv3, with paid Enterprise and Developer editions adding scale, support and extra features. AI assistants can be connected through plugins with the provider of your choice. Pricing for the cloud DocSpace is per admin rather than per user, with a free starter tier. Weak points: the free community server has connection limits, and the mix of product names and editions can be confusing.

Best for: Teams wanting self-hosted, Office-compatible editing inside Nextcloud or similar.
