Change accounts without typing a password

Sign in once, save the account, and switch whenever you want. NEXUS closes the launcher, swaps the login, and opens it again.

  • Steam, Riot Games, Discord, Epic Games and Ubisoft Connect
  • Opens the right profile in Chrome, Edge, Brave or Firefox
  • Passwords are never stored, and saved logins stay on your PC
  • Won't switch while VALORANT, League or a Steam game is running

Set up a new PC with one file

Tick the apps you always install and export one installer. Run it on the new PC and it installs each app through winget, showing progress as it goes.

  • Browsers, launchers, voice chat and everyday tools
  • Keep the file on a USB drive and reuse it on every PC
  • Runtimes finds the Visual C++ and .NET packages games ask for

See your drives, and change them carefully

Every disk is drawn to scale. Shrink a partition by the amount you want to free, or create, rename, format and delete, with guards on anything risky.

  • Windows, EFI and Recovery partitions are protected
  • Format and delete ask you to type the word to confirm
  • Stops if the disks changed since the page loaded
The Disk Manager page, drawing each disk as a bar of its partitions and free space

Everything else in the box

Startup Manager
Turn off the programs that slow down your boot.
