What is DUO?
App for business
DUO goes beyond launching one more window. It is built for people who operate multiple identities inside the same app.
What DUO Does
Drop your .app and DUO analyzes its DNA to prepare the first clone.
Generate instances. Manage sessions like a pro.
Paths are carved out. Sessions are officially separated.
Go live. Rebuild if needed. DUO handles the rest.
Compatibility
DUO does not hide behind vague marketing. It tells you where the real limits are.
Non-App-Store apps, plus messengers, browsers, and workspace tools that respect isolated HOME or Application Support paths.
Apps deeply tied to App Sandbox, app groups, or hard single-instance locks still have meaningful constraints.
When an app does not behave, DUO keeps researching ways to make it work.
