Abaddon
An alternative Discord client with voice support made with C++ and GTK
Alternative Discord client made in C++ with GTK. Abaddon tries its best (though is not perfect) to make Discord think it's a legitimate web client. Some of the things done to do this include: using a browser user agent, sending the same IDENTIFY message that the official web client does, using API v9 endpoints in all cases, and not using endpoints the web client does not normally use. There are still a few smaller inconsistencies, however. For example the web client sends lots of telemetry via the /science endpoint (uBlock origin stops this) as well as in the headers of all requests. Discord likes disabling accounts/forcing them to reset their passwords if they think the user is a spam bot or potentially had their account compromised. While the official client still often gets users caught in the spam filter, third party clients tend to upset the spam filter more often. If you get caught by it, you can usually appeal it and get it restored. -
