Discord

Discord is a free all-in-one messaging, voice and video client that's available on your computer and phone.

This repo hosts the flatpak wrapper for Discord, available at Flathub.

flatpak install flathub com.discordapp.Discord
flatpak run com.discordapp.Discord

Differences in flatpak version

The flatpak version runs in a sandbox to provide better safety and privacy for users.

However, this sandboxing prevents the following features from working:

Game Activity: This flatpak version of Discord cannot scan running processes to detect running games.
There is currently no workaround or solution for this limitation.
Unrestricted File Access: Default sandbox permissions for this package limit Discord to only certain directories, so you can't access your entire Home directory. Currently, this limits which file directories you can attach files from and impacts drag and drop functionality.
This limitation will likely be overcomed eventually, when Electron give us a file picker portal which will allow full access to the filesystem while still restricting unauthorized access.
To work around this now, you can change sandbox permissions of installed flatpak applications (for example, with Flatseal or with flatpak override --filesystem=home com.discordapp.Discord) to give Discord broader file system access, allowing file attachments from more locations.
Rich Presence: See this page if you want to expose Discord's rich presence interface for other applications.

This package enables the flags to run on Wayland, however it is opt-in. To opt-in run:

flatpak override --user --socket=wayland com.discordapp.Discord

To opt-out do the same with --nosocket=wayland.

The Discord app itself is proprietary (closed source).
