One Messenger Hub

One Messenger Hub brings WhatsApp, Telegram, Messenger, Instagram, Discord, Slack, Teams, LinkedIn, email services and more into a single desktop window. Conversations are organized in tabs, with support for multiple accounts per platform through isolated sessions. Built for businesses, support teams, sales teams, entrepreneurs and anyone managing several communication channels, it includes native macOS notifications, unread badges, keyboard shortcuts and local session storage. The app is free to use with one account per platform; a one-time Pro purchase adds multiple accounts and other power features.
