    The most complete chat UI for React Native

    See the files in example-slack-message for an example of how to override the default UI to make something that looks more like Slack, with usernames displayed and all messages on the left. Avatar as user's initials. Localized dates. Multi-line TextInput. InputToolbar avoiding keyboard. Redux support. System message. Quick Reply messages (bot). Typying indicatior react-native-typing-animation. If you decide to specify a text prop, GiftedChat will no longer manage its own internal text state and will defer entirely to your prop. This is great for using a tool like Redux, but there's one extra step you'll need to take, simply implement onInputTextChanged to receive typing events and reset events (e.g. to clear the text onSend). ...

    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.

There are still a few smaller inconsistencies, however. For example the web client sends lots of telemetry...
