Two WhatsApps, two Teams, one window.
Nexus gathers the web apps you keep open all day. Each service keeps its own session, so your accounts stay signed in together and never sign each other out.

Two problems, one tool
and almost nobody solves the second01
Fifty tabs, never the right one
The apps you keep open end up buried in the tab bar, and you hunt for the right one every time. Nexus pins them to a sidebar: one click, or Ctrl+1 to Ctrl+9, and you are there.

your browser, Tuesday 2pm
02, the real differentiator
A browser only holds one account at a time
WhatsApp Web keeps a single session per browser: opening the second account signs the first one out. Teams is no better: Microsoft’s own answer is to open another browser or a private window. Nexus gives every service an isolated session: three WhatsApp numbers and two Teams organisations stay signed in at once, and never sign each other out.

What changes day to day
Native Windows notifications
Real system notifications. Each service mutes independently: work Teams can ring while the friends’ WhatsApp stays quiet.
Unread counts, everywhere
A badge on the service in the sidebar, one on the taskbar icon, one in the tray. The count is there even with the window closed.
Your services, your order
A catalogue of common services with their real logos, plus any custom URL. Drag and drop to arrange the sidebar however you like.
Per-service sleep
A service you are not using gives its memory back. It stays signed in: the next click wakes it exactly where you left it.

Installing takes a minute
Download the installer, run it, pick your services. Nexus updates itself from then on: you will not need to come back here.
Windows 10 and 11 · 64-bit · no account to create
Nexus runs on Chromium 150 and tracks the stable Electron line. That is what decides whether your services still work six months from now. Why the engine version matters
