Celeste is a Twitch chat bot written in C++/Qt. It's purpose is to watch for commands that appear in chat and function as a widget in your OBS scene collection that displays reactions to those commands. It is cross-platform and open source.
The main configuration file is Celeste.conf which lives in ~/.config/Sky-Meyg on Linux, or Celeste.ini which lives in %APPDATA%\Sky-Meyg on Windows. You will need to build an initial one before you can use Celeste. And example looks like the following.
[Authorization]

Token=
JoinDelay=3000
[Window]
BackgroundColor=#d8000000

[Events]

Set Administrator to your Twitch username and Token to your app's OAuth token, which can be generated by following the instructions in the Twitch Developer Documentation for Authentication.
A file named commands.json will be generated in ~/.local/share/Sky-Meyg/Celeste on Linux, or %APPDATA%\Sky-Meyg\Celeste on Windows. It will initially be an empty array. This is where you define the commands the Celeste can recognize and what the reponse will be. Here is an example.
[{
"command": "gandalf",
"description": "Celebrate with Epic Sax Gandalf",
"type": "video",
"random": false,
"path": "/home/herb/Videos/Social Media/Twitch/gandalf.mp4"
},
{
"command": "tiktok",
"description": "Play a random TikTok video from Herb's favorites",
"type": "video",
"random": true,
"path": "/home/herb/Videos/Social Media/TikTok"
}]
