Linux lover? Build Collabora Office and unleash your inner hacker.

Build Collabora Office

This is the Collabora Office Linux app built on Qt6 WebEngine. It’s designed to work the same way as the Collabora Office apps for Windows (windows/) and macOS (macos/).

Linux

Build

Use a separate “online” checkout that is separate from your usual Online builds and checkout the distro/collabora/coda-25.04 branch. Clone the LibreOffice core repository and switch to the distro/collabora/co-25.04 branch. For general build guidance, see the normal build instruction.

It requires what Collabora Online already requires and the additionally following Qt libraries:

Qt6Core
Qt6Widgets
Qt6Gui
Qt6WebEngineCore
Qt6WebChannel
Qt6WebEngineWidgets
QtLinguisttools

Run ./autogen.sh, then configure

./configure \
    --enable-qtapp \
    --with-lo-path=/path/to/core/instdir \
    --with-lokit-path=/path/to/core/include \
    --enable-debug \
    CXXFLAGS="-O2 -g -fPIC"

Adjust the paths to --with-lo-path and --with-lokit-path.

Then run make -j$(nproc) in the top directory. This will result in coda-qt executable in the qt directory.

Run

Usage: ./qt/coda-qt to start without a document, or ./qt/coda-qt DOCUMENT [DOCUMENT...]

e.g. ./qt/coda-qt ../test/data/hello.odt

Debug with Chromium DevTools

export QTWEBENGINE_REMOTE_DEBUGGING=3311

Then run coda-qt and open http://localhost:3311

Flatpak

Building flatpak

There is a flatpak manifest under flatpak/com.collaboraoffice.Office.json.

Install following dependencies for building the flatpak.

flatpak install org.kde.Sdk//6.10 \
                org.kde.Platform//6.10 \
                org.freedesktop.Sdk.Extension.node20//25.08 \
                io.qt.qtwebengine.BaseApp//6.10

Use flatpak-builder to create a flatpak.

Build and install user level: flatpak-builder build-dir com.collaboraoffice.Office.json --install --user --force-clean --ccache
Create a bundle from the build-dir: flatpak build-bundle .flatpak-builder/cache CollaboreOfficeQtApp.bundle com.collaboraoffice.Office
