ONLY OFFICE

ONLYOFFICE is a versatile office suite and collaboration platform designed to provide a comprehensive set of tools for document editing, project management, and team collaboration. It is available as an open-source solution, making it highly customizable and accessible to individuals, businesses, and organizations seeking transparency and control over their software.

At its core, ONLYOFFICE includes a suite of editors for creating and managing text documents, spreadsheets, presentations, and fillable PDF forms. These editors are designed with high compatibility with Microsoft Office formats, ensuring seamless integration into existing workflows. The platform also supports advanced features such as real-time co-editing, version control, commenting, and built-in communication tools like chat and video calls. Users can deploy ONLYOFFICE in various environments—on-premises or in the cloud—and integrate it with popular platforms like Nextcloud, WordPress, or Moodle for enhanced functionality.

ONLYOFFICE's open-source nature is central to its identity. Released under the AGPL 3.0 license for its core components and Apache 2.0 for certain modules like ONLYOFFICE Groups, the platform allows users to access its source code on GitHub. This openness enables developers to modify the software according to their needs, contribute improvements to the community, or integrate ONLYOFFICE into custom applications. The open-source approach also ensures compliance with data sovereignty principles, giving users full control over their data without reliance on proprietary cloud services.

The platform emphasizes security through robust measures such as encryption (at rest, in transit, and end-to-end), GDPR compliance, and flexible access controls. These features make it suitable for industries requiring stringent data protection standards. Additionally, ONLYOFFICE offers tools like CRM modules, project management features with Gantt charts and time tracking, email integration, and calendar synchronization—all of which can be tailored to specific organizational needs.

ONLYOFFICE is a good open-source office suite that combines professional-grade document editing with collaborative tools for teams of all sizes. Its open-source licensing fosters transparency and adaptability while prioritizing security and compatibility with industry standards.
