Collabora Online

Collabora Online is a cloud-based office suite developed by Collabora Productivity, a division of Collabora Ltd, founded in 2011 and headquartered in Cambridge, United Kingdom. Collabora is the leading commercial contributor to LibreOffice and has built Collabora Online as the enterprise-grade cloud version of the LibreOffice desktop suite. The company brings deep expertise in open source document editing, with its engineers maintaining core components of the LibreOffice codebase that powers hundreds of millions of desktop installations worldwide.

The platform provides browser-based editing of documents, spreadsheets, and presentations with full support for ODF (Open Document Format) as its native format, along with strong compatibility with Microsoft Office formats. Collabora Online supports real-time collaborative editing, track changes, comments, and version history. The suite integrates natively with Nextcloud, ownCloud, Seafile, and other file sync platforms via the WOPI protocol, and can be embedded into custom applications. Mobile support is provided through dedicated apps for iOS and Android, ensuring teams can edit documents from any device.

Collabora Online is headquartered in Cambridge, UK, and is available as a self-hosted solution or through certified hosting partners across the European Union. The entire codebase is open source under the Mozilla Public License, giving organizations complete transparency and the ability to audit the code that handles their documents. Collabora Online is widely deployed by European governments, universities, and enterprises that require a GDPR-compliant, vendor-independent alternative to Google Docs and Microsoft 365. Its deep integration with Nextcloud has made it a cornerstone of the European sovereign cloud movement, offering an office suite that is fully controlled by the organizations that use it.
