ONLYOFFICE Docs Reviews for 2025

What is ONLYOFFICE Docs?

ONLYOFFICE Docs is an open-source office suite built for secure, collaborative document editing. It includes full-featured editors for text documents, spreadsheets, presentations, fillable forms, and PDFs, all with 100% compatibility with Microsoft Office formats. Unlike proprietary solutions, ONLYOFFICE gives organizations flexible deployment choices: in the cloud, on-premises, or integrated into existing platforms like Nextcloud, ownCloud, Alfresco, Moodle, Odoo, Confluence, SharePoint, and Redmine through ready-to-use connectors, APIs, and WOPI.

Designed for real-time collaboration, it offers co-editing, track changes, version history, commenting, and e-signatures. Its PDF editor allows annotation, editing, and format conversion, while advanced features include AI assistants, grammar checkers, translation tools, and diagram makers. Available on the web, desktop (Windows, Linux, macOS), and mobile (iOS, Android), ONLYOFFICE ensures cross-platform accessibility.

Security is a core focus, with open-source transparency, GDPR compliance, JWT tokens, and granular access permissions for complete digital sovereignty. Licensing options include a free Community Edition for up to 20 users, an Enterprise Edition for larger organizations, and a Developer Edition for software vendors embedding the suite.

As a cost-effective alternative to Microsoft 365, Google Workspace, LibreOffice Online, and Collabora Online, ONLYOFFICE Docs helps businesses, governments, and educational institutions retain control over their data while enabling modern collaboration.
