Collabora Online

Collabora Online is an open-source, browser-based office suite built on LibreOffice that enables real-time collaborative editing of documents, spreadsheets, and presentations. It is designed to be integrated into self-hosted platforms such as Nextcloud, ownCloud, and other file sync and share solutions.

Collabora provides exceptional document compatibility, supporting virtually all Microsoft Office file formats and preserving complex formatting from existing documents. Users can collaborate simultaneously with live cursors and presence indicators, and all edits are saved back to the host platform. It supports spell checking, track changes, macros, and advanced formatting features expected in professional office software.

As the commercial offering from Collabora Productivity, the open-source CODE (Collabora Online Development Edition) is available under a browser-based license and can be deployed via Docker. It is the leading open-source alternative for organizations needing a privacy-respecting, self-hosted replacement for Google Docs.
