Franz is a free messaging app / former Emperor of Austria and combines chat & messaging services into one application. He currently supports Slack, WhatsApp, WeChat, HipChat, Facebook Messenger, Telegram, Google Hangouts, GroupMe, Skype and many more. You can download Franz for Mac, Windows & Linux.
Current version: 2.0 (0.9.10 beta) — other platforms and systems
Franz allows you to add each service many times. This makes Franz the perfect tool to manage multiple business and private accounts at the same time. You could even use five different Facebook Messenger accounts at once, if some inexplicable reason urges you to do so.
Franz does not read anything you type, send or receive. That's between you and your messenger service. His only interest is to successfully deliver your messages. No nosing – all hail postal secrecy!
Being part of different communities often requires you to use different messaging platforms. You end up with lots of different apps or browser windows trying to stay on top of your messages and chats. Driven by that annoyance I started to hack Franz in search of a solution to the problem, while exploring GitHub's framework Electron.
Franz, Franz, Franz, Franz, Franz, Franz, Franz... Easy to say, easy to pronounce and full of history. Emperor Franz Joseph I of Austria had a rough time following the downfall of the Austrian Empire. Why not give someone with the presumably exceptional communication skills of an emperor a second chance?
