Features
Accessibility-tree snapshots rendered as token-efficient, LLM-readable UI views
Stable element refs (@e1, @e2) for repeatable targeting across runs
`snapshot -i` returns only interactive elements to shrink context
Snapshot refinement flags, e.g. `snapshot -i -c -d 4`
Semantic selectors: `find "Sign In" click` and `find role button click`
Drives real apps on iOS, Android, TV, and desktop targets
Cross-platform runs via --platform ios, --platform android, or --target tv
Switch between simulators, physical QA devices, and TV-class targets
Pin a specific device with --serial, e.g. --serial emulator-5554
Record exploratory sessions to a replayable .ad script with --save-script
Deterministic replay via `agent-device replay`, plus experimental -u selector healing
Typed TypeScript client (createAgentDeviceClient) with simulators.ensure and capture.snapshot
Session lock policy such as 'reject' for concurrent-session safety
Parsed log capture with `agent-device logs mark` and network dumps via `network dump`
Screenshots, screen recordings, airplane-mode toggling, and push notification triggers
Durable execution captures Workflow state at every step with no checkpointing or recovery code
Native SDKs for Go, Java, Python, TypeScript, .NET, PHP, Ruby, and Rust
Activities retry automatically with backoff, four timeout classes, and heartbeating
Signals, Queries, and Updates read and mutate running Workflows mid-flight
Workflow Streams for real-time interactivity with running executions
Durable AI agents via OpenAI Agents SDK and Google ADK running LLM and tool calls as Activities
Standalone Activities as a durable job-queue pattern, GA across six SDKs (2026-09-15)
Serverless Workers for Google Cloud Run, public preview (2026-10-05)
Serverless Workers for AWS Bedrock AgentCore, pre-release (2026-09-18)
Native Task Queue priority and fair distribution without a custom queueing layer
Durable Timers that sleep for months; cron Schedules with backfill and Continue-As-New
Saga pattern via compensating transactions that read like try/catch
Worker Versioning pins Workflows to a version so deploys don't corrupt in-flight runs
Cloud UI Strict Session Mode: 15-minute inactivity timeout, 12-hour max session (GA)
Replay tests validate against real histories; time-skipping tests fast-forward long timers in CI

Frequently Asked Questions

Agent Device vs Temporal AI: which should you choose?

If you need to build reliable, fault-tolerant AI agents that handle long-running processes and recover from failures, Temporal is your pick. If you want a free CLI to let AI agents natively control mobile devices, Agent Device is the go-to. They solve completely different problems; choose based on whether your bottleneck is execution durability or mobile device interaction.

Can Temporal be used for mobile device automation?

No, Temporal is a workflow orchestration platform; it does not control mobile devices. For mobile device automation, use Agent Device.

Is Agent Device suitable for production mobile test automation?

It's designed for prototyping and developer workflows, not production test suites. It lacks extensive reporting and cloud device farm integration.

Does Temporal have a free tier?

Yes, Temporal offers a free self-hosted open-source version. Their cloud service has usage-based billing, with a recent Billable Actions metric for metering.

What integrations does Agent Device support?

No integrations are listed in the documentation. It's a standalone CLI tool.

Can Temporal handle human-in-the-loop workflows?

Yes, Temporal supports human-in-the-loop via signals and pause/resume, making it suitable for workflows that require manual approval.
