dcd live

Start an interactive cloud device session and drive it from your terminal — install a build, run individual Maestro commands or a whole flow, capture screenshots, and dump the view hierarchy. This is ideal for authoring and debugging flows against a real cloud device.

WARNING

Live is in beta and is billed at $0.03/min, excluding Sales Tax. Access is limited and by request only. If you would like to try Live, please contact support to request access. dcd live works with a dcd login session or an API key.

dcd live <subcommand> [flags]

A typical session: start a device, install a build, interact, then stop.

dcd live start --platform android --wait
dcd live install --session <name> --app-binary-id <id> --wait
dcd live run --session <name> path/to/flow.yaml
dcd live stop --session <name>

Every subcommand (except start) takes a --session <name> flag identifying the session, and accepts --api-key / --api-url.

dcd live start

Start a new live device session. Prints the session name and a console URL you can open to watch the device.

Flag	Description
--platform <android|ios>	Device platform (default: android)
--app-binary-id <id>	Binary upload ID to install on the device at start
--device-locale <locale>	Device locale, e.g. de_DE
--android-device <device>	Android only. Device profile: pixel-6, pixel-8, pixel-10, pixel-10-pro, pixel-10-pro-xl or pixel-11
--android-api-level <level>	Android only. API level, e.g. 34 (must be passed together with --android-device)
--wait	Block until the device is ready to accept commands

dcd live install

Install a binary on a running session's device.

Flag	Description
--session <name>	Required. Live session name
--app-binary-id <id>	Required. Binary upload ID to install
--wait	Block until the device is ready again after installing

dcd live exec

Execute one or more Maestro YAML commands against the session.

Flag	Description
--session <name>	Required. Live session name
--yaml <commands>	Inline Maestro YAML commands, e.g. --yaml "- launchApp"
--file <path>	Read the Maestro YAML to execute from a file (alternative to --yaml)
--wait	Wait for the device to be ready before executing

Pass either --yaml or --file, not both. dcd live exec exits 0 even when the commands fail, so check the printed result.

dcd live run

Run a whole Maestro flow file against the session. The flow's appId: header is handled automatically.

Flag	Description
<flow-file>	Required. Path to the Maestro flow file (positional argument)
--session <name>	Required. Live session name
--timeout <seconds>	Max seconds to wait for the flow to finish (default: 600)
--wait	Wait for the device to be ready before running

dcd live run exits 2 if the flow fails, or if it's still running when --timeout is reached (see Exit Codes).

dcd live screenshot

Save the current device screen to an image file (PNG or JPEG, matching the device format).

Flag	Description
--session <name>	Required. Live session name
--output <path>, -o	File path to write to (default: live-screenshot.<ext>)

dcd live hierarchy

Dump the current view hierarchy — the selectors (text, accessibility labels, resource IDs) you can tap and assert on.

Flag	Description
--session <name>	Required. Live session name
--json	Output the raw hierarchy as JSON
--output <path>, -o	Write the output to a file instead of stdout

dcd live status

Show a session's status — platform, readiness, current device phase, device model, locale, and time until auto-cancel.

Flag	Description
--session <name>	Required. Live session name

dcd live stop

Stop a live session.

Flag	Description
--session <name>	Required. Live session name
