Nextcloud with Collabora Online Office on Ubuntu 24.04 LTS

Overview

Nextcloud is the open source content collaboration platform organisations run to keep file sync and share, calendars, contacts and team workflows on infrastructure they control. On its own it stores and shares documents; to edit them in the browser it needs a separate office server speaking the WOPI protocol, which is the piece most people end up assembling by hand.

This image ships that assembly finished. Nextcloud Server comes pre installed and unmodified with the Nextcloud Office app enabled, and a native Collabora Online Development Edition (CODE) server runs on the same machine, so Writer, Calc and Impress documents open for real time collaborative editing in the browser with no external service and no Docker layer. Both halves are wired over the loopback interface: Nextcloud talks to the office engine locally, the office engine fetches and saves documents through a local WOPI callback, and the browser reaches both through one TLS front door on the same origin.

CODE is Collabora's free development edition. As configured here it places no limit on concurrent users or documents; what it lacks is Collabora's commercial support contract, and its welcome and feedback prompts cannot be switched off. Organisations that want the supported Collabora Online build can point the Nextcloud Office settings at their subscription server without changing anything else in the image.

Common uses

• Self hosted file sync and share with in browser office editing
• Real time collaborative document editing for a team on infrastructure you control
