Collabora Online

Collabora Online is an open source online office suite developed by Collabora Productivity, a division of Collabora. It is based on LibreOffice Online. The web application allows collaborative editing of text documents, spreadsheets, and presentations.
==History==
The former LibreOffice development team from SUSE joined Collabora in September 2013 forming the subsidiary Collabora Productivity. In 2015 Collabora together with IceWarp announced the development of and enterprise-ready version of LibreOffice Online meant to compete with Microsoft 365 and Google Docs. In December 2015, the company's partnership with ownCloud and release of CODE (Collabora Online Development Edition) was announced on Joinup. On 2 June 2016, the company released Collabora Online 1.0 “Engine”, which the company calls the first production grade version of Collabora Online. On 2 November 2016, the company released CODE 2.0 which became a collaborative real-time editor; previously only one person was able to edit, others in the document were only observers. In December 2017, version 3.0 of the Collabora Online Development Edition (CODE) has been released.
In October 2020 Collabora announced the move of its work on Collabora Online from The Document Foundation infrastructure to GitHub.
==Platforms==
Collabora Online is delivered as a web application and can be used with any modern browser. For Android and iOS devices, native apps were released in 2020, which also work offline. A version running on Chromebooks and allowing to store documents locally is also available.
==Features==
Collabora Online allows collaborative real time editing text documents, spreadsheets and presentations in the browser. Unlike Google Docs or Office 365 the software is not offered as a cloud service. Instead, users can install it in their own environment. Since the release of Nextcloud Hub 19, this is also possible from within a chatroom of Nextcloud's built-in video-conferencing tool Nextcloud Talk. It supports the Open Document Format (.odt, .odp, .ods) as well as all newer Microsoft formats (.doc, docx, .ppt, .pptx, .xls, xlsx).
==Technology==
The core of Collabora Online is written in C++ just like the core of LibreOffice. It uses the LibreOfficeKit, a programming interface that allows the reuse of most of the existing LibreOffice code and the saving, loading and rendering of documents. The basic principle of Collabora Online is that documents never leave the server. The parties working on the documents see tile-rendered images of the document and send their changes back to the server. The visible user interface of Collabora Online is written in JavaScript. For file access and authentication with a file hosting services, Collabora Online uses the WOPI protocol developed by Microsoft. This means that Collabora Online can - in theory - be used with any instance allowing a Microsoft 365 integration.
==Reviews==
Collabora Online was discussed in various online and print publications. In December 2016 the tech website Softpedia mentioned the availability of collaborative editing in version 2.0 and the integration with Owncloud, Nextcloud and other FSS solutions. The technology website ZDNet reported in June 2020 that Collabora Online from version 19 of Nextcloud will be delivered as a standard office package and that within the native video conferencing software Talk direct editing of documents is now possible. The technology blog OMG! Ubuntu! covered the release of the Android & iOS apps pointing out the possibility to use them in offline mode. In September 2020 Linux Magazine compared Collabora Online with OnlyOffice, mentioning the flexibility and platform independency of both tools and pointing out large set of features Collabora Online draws from LibreOffice.
