Fractal is described as 'Matrix messaging app for GNOME written in Rust. Its interface is optimized for collaboration in large groups, such as free software projects' and is an app in the Social & Communications category. There are five alternatives to Fractal for a variety of platforms, including Android, iPhone, Android Tablet, iPad and Linux. The best alternative is Element. It's not free, so if you're looking for a free alternative, you could try Matrix.org or Librem Chat. Other great apps like Fractal are Revolt (for Riot) (Free, Open Source) and Dust (Free).
Element is a secure collaboration and messaging app based on the Matrix protocol. It’s decentralised to deliver digital sovereignty, and based on an open standard for easy connections and interoperability. It is end-to-end encrypted by default.
Matrix defines a set of open APIs for decentralised communication, suitable for securely publishing, persisting and subscribing to data over a global open federation of servers with no single point of control.
Librem Chat – end-to-end encrypted chat, VOIP, and video calling used by millions of people * Chat rooms * Share images, videos, and files * Make voice and video calls * Keep your conversations secret with end-to-end encryption * Free and open-source software
Revolt is a small application which wraps Riot to provide better integration with desktop environments in general, and GNOME in particular: * Having Riot as a “standalone” application with its own window, launcher, icon, etc. instead of it living in a browser tab.
