Franz is not a messaging app *specifically* for Windows, but rather a

multi-platform desktop app

that allows you to connect and manage multiple messaging and communication services in one unified interface. It[SQ]s available for Windows, macOS, and Linux.

Think of it as a central hub for all your chats. You can add accounts for services like WhatsApp, Slack, Telegram, Facebook Messenger, and many others, all within the Franz app window. This avoids having to juggle multiple individual apps.

So, while it *runs* on Windows, its key feature is its ability to consolidate numerous messaging services, not being a messaging service itself.
