Questions
What is the Cleo Local Agent?
A small background app that runs on your computer. It bridges the gap between your browser and a USB-connected phone, letting ZERO install apps and run tests on real devices.
Do I need it?
Only if you want to test on a physical device connected via USB. For cloud emulator testing, you don't need it — ZERO uses a cloud Android emulator by default.
Does it work with iOS?
Yes, but iOS testing via USB requires a Mac with Xcode installed. For a simpler iOS testing experience, we recommend using TestFlight instead — ZERO can submit your app there directly.
Is it safe?
The agent only communicates with your browser on localhost. It doesn't send data to any external servers. It uses ADB (Android) and ios-deploy (iOS) — standard developer tools.
Can I uninstall it?
Yes, at any time. Uninstalling the agent just means ZERO will use the cloud emulator for device testing instead.
Don't need USB testing? No worries — ZERO uses a cloud emulator by default.
The Local Agent is optional.
