Open Source Steam Client and Discord Client

Does any of you know a open source steam/discord client?
Would be a plus if Debian has it in their repository

There aren’t any other great alternatives to Steam, if you use Discord, Mumble is a good choice. I would also like to emphasize; just because it is open-source, that doesn’t mean its a good application. You would have to rely on games being compatible, and includes their own launcher.

there is a GOG clinet for linux (its open source if iam right) maybe use GOG instade of steam

Mumble is a good choice

Are in Mumble also Porn sharing channels? Like Discord?

There’s a Discord bridge, you might want to find out about it, seems promising.

I would change Mumble for Riot as I prefer it
