Are there any open source Steam clients? Maybe it can be like Heroic, because desktop Steam is technically browser with specific website opened.
Steam and Valve has great Linux support, but it would be interesting to try alternative open source client.
The only open source client that I know that worked with Steam is for bridging Steam’s chats and notifications with IRC. It’s called Bitlbee.
And i’ve stopped using it a few years ago because IIRC it was a pain to keep the authentication working with Steam. They thought hackers were accessing my account or something like that, and I kept having to disable security “features” just in order to stay logged in.
I assume an open source client not endorsed by Steam would have the same issue.
