Isolated sessions
Each account signs in separately and keeps its own cookies and login, so accounts never mix.
One window, every account
Every chat account in one window
Stop switching phones and browser tabs. Sign in to all your WhatsApp, Telegram, LINE, Messenger, TikTok, Zalo and X accounts and work them side by side, each kept completely separate.

Questions
How many accounts can I run at once?
As many as your plan allows: 5 on Starter, Pro and Business (Pro and Business can add more), unlimited on Enterprise.
Is WhatsApp Business supported?
