A Matrix chat client for the GNOME Desktop Environment

Fractal is a Gtk+ client written in Rust.

Come to talk with us in Matrix:

Main repository:

How to Build:

You need meson and ninja to build this project. Rust and cargo are also needed.

./configure --prefix=/usr/local make sudo make install

On MacOS, you will need to:

brew install gtk3+ dbus bash

  1. empirically needs 3.22.19 or later of gtk3+
  2. ...and run configure as:

/usr/local/bin/bash -c ./configure --prefix=/usr/local

You may also need to comment out the block in ./fractal-gtk/src/ as apparently notification.wait_for_action is missing on MacOS.

The origin of Fractal:

This project is based on ruma-gtk

Instead of using RUMA Client, Fractal calls directly to the REST API.

The first version of this project was called guillotine, based on french revolution, in relation with the Riot client name, but it's a negative name so we decide to change for a math one.

The name Fractal was proposed by Regina Bíró.
