Agent Device

Free open-source CLI giving AI agents structured, token-efficient control over real mobile and desktop devices.

61/100MonitorFreeFree

A smart, early-stage open-source tool that fills a real gap: cheap, structured mobile UI access for LLMs. Worth trying if you build agent workflows for native mobile or TV apps, but expect a lean ecosystem and concise docs. Unlike Playwright or Appium, its token-efficient snapshots make it uniquely suited for agent contexts. If you need production-grade test reporting or extensive community support, consider Appium or a cloud device farm (e.g., BrowserStack).

About Agent Device

FreeAdvancedAPI availableCLI

Agent Device is a free, open-source CLI from Callstack that gives AI agents structured, programmatic control over real iOS, Android, TV, and desktop devices. Instead of relying on full screenshots or verbose UI dumps, it exposes the accessibility tree as token-efficient snapshots with stable element references (like @e2). That keeps LLM context small and makes it fast for agents to understand and act on native app UIs. You can tap, fill, navigate, record sessions, and capture evidence across platforms using a unified command set, on simulators or physical devices. It's built for developers integrating mobile and TV app automation into agentic workflows, unlike browser-focused tools like Playwright or Puppeteer. At the heart of Agent Device is a simple workflow: agents take a snapshot to see the screen, then act using stable refs or semantic selectors (by text, label, or role). Commands like `agent-device snapshot -i` list only interactive elements, and `agent-device find "Sign In" click` makes flows readable and resilient. The tool is cross-platform by default, so the same agent logic works on iOS, Android, and TV targets with one mental model. Beyond basic interaction, Agent Device supports exploration-to-E2E replay. Agents can record a session, save it to a script, and replay it deterministically later. An experimental auto-updating flag (-u) can even heal stale selectors on the fly, turning exploratory QA into regression infrastructure. For debugging, you get parsed logs, network dumps, screenshots, and screen recordings, plus environment and push notification triggers. The tool includes a fully typed TypeScript client for programmatic integration, plus official skill packs that give agents canonical workflows and targeting rules. You can run it locally or via a remote proxy in cloud sandboxes, making it a flexible fit for agent pipelines. Free and open source, it's a pragmatic choice for teams that need real device verification without the overhead of cloud

Behind the Verdict

Most agent-to-app tooling assumes a browser. Agent Device takes a different bet: give agents a structured, token-efficient view of native mobile and TV UIs, and they can do real QA, bug reproduction, and regression work. That bet pays off in practice—the accessibility-tree snapshots with stable refs keep context small and make flows readable. If you're building an agent that must click through a native app, this is worth a serious look. Where it shines is exploration-to-E2E replay. An agent can poke around an app, record a session, and turn it into a replayable .ad script. That's a neat bridge between discovery and regression testing. The auto-healing flag (-u) is experimental but promising—it could save you from chasing flaky selectors. The tradeoff: you're trading a mature ecosystem for a lean one. Docs are concise, community is small, and you won't get production-grade test reporting out of the box. If you need that, Appium or cloud device farms are the established route. But if you're an agent developer who needs cheap, direct device control, Agent Device's CLI and TypeScript client are refreshingly straightforward. Compared to Playwright-style browser automation, it's a different animals. Agent Device gives you the same mental model but for native and TV apps. That's its niche—and it fills it well. If you're on a platform team integrating device automation into agent pipelines, the remote proxy means it can run in cloud sandboxes, so your agents work anywhere. Watch out for the learning curve if you're not comfortable with CLIs. And the skill packs—while handy—assume you're using agents that can consume them. If you're working with a non-technical team or expect GUI-based control, this isn't your tool. In practice, we'd reach for Agent Device when we need

Real-world workflow fit

Concrete scenarios for the personas Agent Device actually fits — and what changes day-one when you adopt it.

Mobile QA engineer

You're asked to explore a new iOS app build for bugs. Instead of a manual pass, you use agent-device to snapshot the screen, list interactive elements, tap through flows, and record a session.

Outcome: You catch a crash in the login flow, capture logs and a screen recording, and save the session as a replayable script—turning exploration into a regression test.

AI agent developer

You're building an agent that should verify a React Native app's state after each code push. You integrate the typed TypeScript client to boot a simulator, open the app, and take a snapshot.

Outcome: Your agent reads the snapshot (only interactive elements) and asserts the correct screen state, sending you a pass/fail notification—all in a few lines of code.

Platform engineer

You need to run agent-driven UI checks across iOS, Android, and Android TV in a CI pipeline. You install agent-device in a cloud sandbox and use the remote proxy.

Outcome: Your CI job uses the same CLI commands to navigate each platform, takes snapshots, and records video evidence—no extra fees, just a free CLI.

Use Cases

Limitations

  • Agent Device is a CLI tool that requires technical expertise; it does not provide a graphical interface.
  • It relies on device accessibility trees, so apps with poor accessibility support may produce incomplete snapshots.
  • The tool is relatively new with limited community resources.
  • The experimental auto-healing feature may not be reliable in all scenarios.

Ideal for

Developers and QA engineers who want a free, scriptable way to control real devices for agent workflows, especially those building agentic QA or exploration tools without a budget for device farms.

What this tier adds

The sole tier—free, open-source CLI with all features: snapshots, semantic refs, recording, replay, and debug tooling. No hidden costs, but no enterprise support either.

Where the pricing makes sense

The company stage and team size where Agent Device's pricing actually pencils out — and where peers do it cheaper.

Agent Device is completely free and open source, making it a cost-effective choice for startups and indie devs compared to Appium (free but more complex) or cloud device farms like BrowserStack (monthly fees). If you need heavy reporting or managed device infrastructure, you'll pay elsewhere.

Setup time & first value

How long it actually takes to get something useful out of Agent Device — broken out by persona, not the marketing-page minute.

For a developer familiar with npm and CLIs, you can install (`npm install -g agent-device`) and run `agent-device snapshot` on an emulator within 10 minutes. If you need to set up the TypeScript client or skill packs, add another 20 minutes. Non-technical users should expect to spend an hour or more just getting orientation.
