DUO for Mac

Run as many

Stop the sign-out dance.
DUO was built for macOS users who need to run one app as multiple isolated clones.

Limitless Instances

Multiply your apps. Scale your workspace as fast as you can click.

Absolute Isolation

Zero cross-talk. Every clone lives in its own pristine, isolated world.

No More Sign-out

DUO handles the messy part.
Save the time you lose signing out and back in.

What is DUO?

Move beyond app limits

App for business

One app is rarely enough.

DUO goes beyond launching one more window. It is built for people who operate multiple identities inside the same app.

  • Use each cloned app as independently as you need.
  • DUO does not need to stay open.
  • Once a clone is prepared, you can keep working without reopening DUO.

What DUO Does

DUO is short and clear

01

Pick

Drop your .app and DUO analyzes its DNA to prepare the first clone.

02

Multiply

Generate instances. Manage sessions like a pro.

03

Isolate

Paths are carved out. Sessions are officially separated.

04

Launch

Go live. Rebuild if needed. DUO handles the rest.

Compatibility

Where it works well and where limits still exist

DUO does not hide behind vague marketing. It tells you where the real limits are.

Best fit

Non-App-Store apps, plus messengers, browsers, and workspace tools that respect isolated HOME or Application Support paths.

Still limited

Apps deeply tied to App Sandbox, app groups, or hard single-instance locks still have meaningful constraints.

Still evolving

When an app does not behave, DUO keeps researching ways to make it work.
