Mobile tooling for agents

Give and any coding agent a complete interface to iOS and Android simulators.

Free & open source · iOS and Android

Agentsims lets agents observe⁰¹the screen, act⁰² on the device,and verify⁰³ every action.

Observe the app

A compact accessibility tree gives the agent exact elements and references. Screenshots provide visual context when needed.

Act precisely

Tap, type, swipe, scroll, and long-press by element or coordinate across iOS and Android.

Verify the result

Agentsims waits for the interface to settle and returns fresh state, so the agent can choose the next action.

Use it yourself or hand it to an agent.

Developers get every running iOS simulator and Android device in one browser, with screenshots, recordings, settings, and accessibility inspection.

Give the CLI and skill to any coding agent. It can inspect, control, and verify your app through the same workspace, with React Native source context and a trace of every action.

Command traces: Every operation is recorded with its captured evidence. Open the trace panel, or run agentsims trace start. See traces.
App and device logs: iOS, Android, and React Native logs in one panel, with search, filters, and pause. In a terminal: agentsims app-logs --follow.
Simulator settings: Set appearance and location on iOS. Set network, battery, locale, density, and emulator snapshots on Android. See settings.
Camera injection: Send a host webcam to the device camera to test scan and capture flows. See camera input.
App permissions: Grant, revoke, and reset runtime permissions on both platforms: agentsims permissions grant camera.
Screen recording: Record any device to video. A rotation starts a new segment: agentsims record start --out run.mp4.
Annotations: Select a target on a phone and write a note beside it. Copy the notes as one prompt for your agent. See annotations.
React Native source: With the optional Metro integration, accessibility elements show component names and source locations. See the setup guide.
