# Abaddon (open-source chat app)

> Abaddon is a free, open-source chat app for Windows, macOS and Linux. An alternative Discord client with voice support made with C++ and GTK 3. It has 2,224 GitHub stars and is released under the GPL-3.0 license. Its source code is on GitHub at uowuo/abaddon.

1 - 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.
