+You should also be able to run Briar GTK without Flatpak.
+For this, you have to install Java, the
+[Python dependencies](requirements.txt) and Briar Headless.
+Once you've done this, change the path of the Briar Headless
+jar in [src/briar/gtk/define.py](src/briar/gtk/define.py),
+build it with _meson_ and start Briar GTK.
+Keep in mind this wasn't tested so far.
