Kagemusha

Kagemusha wraps a website in a Mac app that runs on a browser you've already got, which can be Chrome, Brave, Edge, Vivaldi or three others.

Each app carries its own icon, its own window and its own profile, so two accounts of one service sit open side by side and neither one knows the other exists.

The wrapper wasn't the hard part. Chrome updates itself every few weeks, and apps built this way break when the files underneath them move. These check themselves when they launch and repair the link. The app you made in February still opens.

Over 300 presets, so you're not pasting a URL and hunting for an icon every time.

Three apps free, 24.99 after that, macOS 12 and later.

If you already run some sites as their own apps, which one did you do first?
