Practical overview
When it fits
Use Agent Device when an AI coding agent needs to interact with a running application and verify a change, reproduce a failure, capture evidence or turn a working interaction sequence into a repeatable workflow.
Who it is for
- Developers using AI coding agents for application development.
- Teams building agent-based testing or verification workflows.
- Node.js developers integrating application automation into orchestration tools.
- Engineers who need screenshots, logs, traces or other evidence from application runs.
Documented uses
- Give a coding agent live access to an application during development.
- Inspect application state through accessibility snapshots, refs, selectors and React Native component trees.
- Drive visible interfaces with taps, presses, field entry, scrolling, gestures, waits and assertions.
- Collect debugging and verification evidence such as screenshots, video, logs, traces and performance data.
- Save repeatable workflows for local use or CI and export strict Maestro YAML when required.
Requirements & limits
The project is publicly available as an MIT-licensed repository. The quick-start documentation requires Node.js 22.12 or newer, and web automation requires Node.js 24 or newer. Target-specific requirements are documented separately.
- Choose the CLI when an agent or developer can run shell commands directly.
- Choose MCP when the coding agent connects to structured tools through the official stdio server; the complete MCP tool schema and configuration details are not specified here.
- Choose the typed Node.js API when automation must be called from Node.js orchestration or an agent runtime.
- Accessibility labels, roles and test IDs affect interaction reliability because agents use accessibility snapshots and refs.
- Use screenshots or video alongside accessibility data when the target exposes limited accessibility information.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
