Getting started · What Storage Studio is
Is there a Windows or Linux version of Storage Studio?
Short answer: Storage Studio is Mac-only. A free companion app, Storage Studio Bridge, installs on a Windows PC to connect it to your Mac for shared folders and clipboard; other platforms aren't available yet.
Storage Studio itself is a Mac app — it runs on macOS only.
For your other devices there's a free companion app, Storage Studio Bridge, which you install on the other device to connect it to your Mac: it can share that device's folders with Storage Studio and share your clipboard both ways. Bridge is available for Windows; the manual lists other platforms as not available yet.
See Bridge & devices for how connecting a device works.
