Self-hosting is supported through standalone deployment or Docker-based setups, with options for direct HTTPS or reverse proxy use. YAGPDB is useful for communities that want a powerful general-purpose Discord bot with deep customization and many built-in modules.

chatanalytics.app is a privacy-focused tool for turning exported chat histories into interactive analysis reports. It supports exports from platforms such as Discord, Messenger, Telegram, and WhatsApp, depending on the available export format. The app generates a single HTML report with statistics, graphs, timelines, emoji analysis, links, calls, interactions, language data, and sentiment information. Its main privacy advantage is that chat data stays in the browser while reports are generated. Users can also run it from the command line or self-host it with Docker. It is useful for people who want to explore conversation patterns without uploading private messages to a third-party analysis service.

Connect to and interact with Twitch chat (IRC) from Node.js or a browser. Control the delay in milliseconds between JOIN requests when using the channels array option. Minimum of 300 milliseconds. If the identity has special permission from Twitch for a higher join rate then you should implement your own calls to the client.join method. Disable receiving JOIN/PART events for other users. Good for decreasing network traffic when joining lots of channels or you don't care about this data. After a threshold per channel Twitch stops sending this data so it may not be necessary for all cases. Channels to automatically join upon connecting. The rate of joins is controlled by the options.joinInterval option. Automatically reconnect the client if it gets disconnected for any reason. Sometimes Twitch will request the client to reconnect and tmi.js will disconnect and reconnect even if this option is set to false.
