Profile a running app's CPU, memory, and React render performance with the conductor CLI, and read crash reports. Use when investigating slowness, jank, memory growth or leaks, excessive React re-renders, or when an app has crashed and you need the crash report.

Boot, list, and manage devices and app installs for the conductor CLI — iOS simulators, Android emulators, tvOS simulators, and Playwright web browsers — plus sessions, the warm-driver daemon, and the parallel device pool. Use when starting or stopping a simulator/emulator/browser, installing or launching an app, setting up the web driver, attaching to an already-running browser over CDP (e.g. an Electron app / its webviews), keeping the driver warm, or coordinating multiple devices for parallel agents.
Drive a running iOS simulator, Android emulator, tvOS simulator, or Playwright web app with the conductor CLI. Use when launching apps, tapping UI elements, typing text, scrolling/swiping, performing gestures, pressing hardware/keyboard keys, opening URLs or deep links, navigating back, or verifying an app change in the real running app.
Author and run Maestro-compatible YAML flows and command sequences with the conductor CLI, including recording flows from live interactions and sharding them across devices. Use when scripting a repeatable multi-step app journey, running an existing Maestro flow, recording a flow by interacting with the app, or running flows in parallel across booted devices.
Read the live UI state of a running app with the conductor CLI — view hierarchy, accessibility snapshot, screenshots, focused element, and element refs. Use when you need to see what's on screen, find an element's id/text/coordinates, take a screenshot, check focus, or assert that something is (or isn't) visible before or after acting.
Inspect a running app's JS runtime, logs, and network with the conductor CLI — evaluate JS in React Native (Hermes) or the web page, dump the React component tree, read console/Metro/device logs, and inspect or issue HTTP requests. Use when debugging app behavior, reading logs, evaluating expressions in the live runtime, inspecting React components, or examining network traffic.

| description | Profile a running app's CPU, memory, and React render performance with the conductor CLI, and read crash reports. Use when investigating slowness, jank, memory growth or leaks, excessive React re-renders, or when an app has crashed and you need the crash report. |
Measure a running app's performance and inspect crashes.
| Command | Purpose |
|---|---|
conductor profile cpu --duration <s> [--out <path>] | Record a CPU trace (iOS: xctrace, Android: simpleperf) |
conductor profile memory --track <s> [--interval ms] [<appId>] | Sample memory for N seconds, report deltas |
conductor profile react start / profile react stop [--top N] | Install a React commit-profiler hook, then summarize captured commits |
| Command | Purpose |
|---|---|
conductor memory [<appId>] | Device + app memory usage |
conductor memory --objects | Include per-class object counts (iOS heap; slower) |
conductor memory --leaks | Run leak detection (iOS only; slow, can pause the app) |
conductor memory --save <name> / --diff <name> / --diff <name> --vs <other> | Snapshot and diff memory reports |
conductor memory --filter <regex> / --growth-only / --top <n> | Narrow object/class tables (great for leak-hunting) |
Typical leak hunt: memory --save before, exercise the screen, then
memory --diff before --growth-only.
| Command | Purpose |
|---|---|
conductor crashes list [--app <bundleId>] [--since <duration>] | List recent crash reports (iOS host + Android logcat) |
conductor crashes show <id> | Print a specific crash report |
conductor crashes tail | Stream new crash reports as they appear |
--json to parse reports programmatically.--duration / --track and avoid leaving crashes tail running.
