What is a cloud Android phone?

A cloud Android phone is an Android phone that runs on a server. You see its screen in the browser and control it by touch, keyboard, API or ADB. Apps and data stay on the device between sessions.

Screenshots and UI tree

Every step can return a fresh screenshot and the elements on screen with their bounds, so you see exactly what the agent saw.

How observe works

Webhooks

Get a call to your server the moment a job finishes, with its result, so your stack reacts on its own.

Set up webhooks

Regions

Devices run in Germany and Finland today, with the US and Asia next.

Where phones run

AI agents

Give an agent an Android phone in the cloud: it sees the screen, taps and types through MCP or the API.

Phones for AI agents

Dashboard

Live screens in the browser, a wall of devices at once, tasks, schedules, apps and billing in one place.

Use it in your browser

API and ADB

Every action is a REST call, and ADB is one command away through a relay locked to your IP.

Control it by API or ADB

By hand, by API, or by asking.

The dashboard, the API and ADB reach the same devices through the same calls.

DashboardA live screen in the browser with touch and keyboard.
REST APICreate, start, stop and install with plain HTTP calls.
ADBInstall, shell and logcat through a secure relay.
AI agentsGive a phone a task in plain words, or let your agent drive the screen step by step.

# create a device
curl -X POST https://api.clousd.com/v1/devices \
  -H "Authorization: Bearer $CLOUSD_KEY" \
  -d '{"profile":"MODEL"}'

# 202 Accepted
{ "name": "c3f9a41d2",
  "state": "starting" }

# enable ADB for your IP for 24 hours (dashboard or API), then:
adb connect relay.clousd.com:27001
adb -s relay.clousd.com:27001 shell clousd-login a1b2c3
login ok

adb -s relay.clousd.com:27001 install app-release.apk
adb -s relay.clousd.com:27001 logcat -d | tail

# the same smoke test on 20 devices at once
curl -X POST https://api.clousd.com/v1/runs \
  -H "Authorization: Bearer $CLOUSD_KEY" \
  -d '{"devices":["c3f9a41d2","c81d07e5a", ...],
       "task":"Open com.example.app and tell me what the first screen shows"}'

# 201 Created - each phone answers in its own run

Questions about cloud Android phones

What is a cloud phone?

An Android phone that runs on our servers. You see its screen in the browser and control it with touch, keyboard, the API or ADB, and it keeps running when you close the tab.

How do I see what my agent is doing?

Open the device in the dashboard and watch its screen live while the agent works, or put several devices side by side in Multi-view. From code, every step can return a fresh screenshot and the UI tree of the screen, and a webhook tells you when a task is done.
