Beginning with Version 3.5 LibreOffice can be launched as a web server. This allows using LibreOffice online within a web browser. A short demonstration is available here.



  • A Linux server
  • A recent version of gtk3. A backport for openSUSE 12.1 can be found here, but if you have all the current updates installed it should just work out of the box.
  • gtk3 with broadway support (for archlinux aur/gtk3-broadway)

Compiling LibreOffice

Since online support is not production ready yet, it is not included in the regular packages of LibreOffice 3.5. Therefore it's necessary to build LibreOffice from scratch. For information how to download the sources and compile them see here.

To ensure the required gtk3 backend is used, add --enable-gtk3 as an option. For now it is recommended to add --without-java as well.

Running LibreOffice in server mode

After successfully building launch LibreOffice with the following commands:

Now point your web browser to http://<servername>:8080 - if you're testing locally that'd be http://localhost:8080 of course.
