It depends on the bridge and protocol. IRC is as straightforward as any other IRC client. WhatsApp needs to run an actual WhatsApp client so you'll need an online iOS/Android device or run it a VM or emulator. Not sure about Discord. EDIT: If you can do without Discord DMs, you don't even need to run the bridge yourself or supply discord credentials - just invite a bot to a discord server if it isn't already https://t2bot.io/discord/ https://t2bot.io/discord/ (Obviously if you're concerned of privacy you wouldn't be having those conversations on Discord in the first place)
