Formerly known as TeamLab, OnlyOffice is a free office suite software developed by Ascensio System SIA, a technology company headquartered in Riga, Latvia.

With the rapid advancement of technology, particularly in cloud computing, our daily activities have become easier. Nowadays, cloud-based applications are increasingly common, one example being web office applications. Before the era of cloud computing, office applications (the most famous being Microsoft Office, Kingsoft Office/WPS Office, LibreOffice, OpenOffice, etc.) had to be installed on a computer or laptop before they could be used for creating documents, presentations, or tables/graphs.
OnlyOffice is a cloud-based office application that helps users manage documents, projects, CRM, teams, and customer relations all in one place. In other words, you no longer need to open multiple applications to handle different tasks. OnlyOffice delivers a multi-feature system to organize every stage of work, boosting productivity and optimizing performance.
OnlyOffice Desktop Editor is an office suite that enables users to create, view, and edit documents, spreadsheets, and presentations without an internet connection. It supports all popular formats such as: DOC, DOCX, ODT, RTF, TXT, PDF, HTML, EPUB, XPS, DjVu, XLS, XLSX, ODS, CSV, PPT, PPTX, and ODP.
An online mode is also available, allowing you to connect your OnlyOffice app to the cloud or a local server (with both a free open-source server version and a Community Edition available). This mode provides full access to collaboration features, making it especially valuable for offices and companies looking to implement it in their workflow.
Currently, users can integrate OnlyOffice with ready-made plugins for Nextcloud, ownCloud, SharePoint, Alfresco, and Confluence. Additional integrations are available with platforms such as eXo, PowerFolder, Seafile, CommuniGate, and Moodle.
