Multi Instance for Claude Desktop lets you run several separate copies of Claude Desktop at the same time \u2014 one per project, client, or account \u2014 instead of juggling everything inside a single window.\n\nHOW IT WORKS\nCreate as many instances as you need. Each one gets its own profile, its own login/session, and its own color, so your work never mixes. A desktop shortcut is made for every instance, so you launch the right one with a single double-click. Open three, four, five at once \u2014 side by side.\n\nINSTANT AND LIGHTWEIGHT\nCreating a new instance takes seconds and uses almost no disk space. Name it, pick a color, and you're done. You can even choose exactly where each instance is stored \u2014 keep a heavy one on another drive if you like.\n\nCOWORK \u2014 ON DEMAND, NOT BY DEFAULT\nClaude's CoWork (computer-use) workspace is large (~8.6 GB). Most people don't need it in every instance, so this app never copies it automatically. New instances cost 0 GB. When you actually want CoWork in a specific instance, click "+ CoWork" and the workspace is set up just for that one \u2014 so you only spend the disk space where you truly use it.\n\nALWAYS UP TO DATE\nWhen Claude Desktop updates, your instances follow. They update automatically, and there's a one-click Update button in the dashboard if you ever want to do it yourself. No instance is left stuck on an old build.\n\nSIMPLE MANAGEMENT\nEverything lives in one clean dashboard: create, open, enable CoWork, or delete an instance \u2014 each action is a single click.\n\nWHO IS THIS FOR\nAnyone who uses Claude Desktop for more than one thing: consultants juggling multiple clients, developers with several projects, people who keep work and personal accounts separate, or teams sharing a machine.\n\nRequires Claude Desktop installed. Windows 10 (1809) or later.
