SimDeck

Control simulators from your browser, CLI, and agents

npm i -g simdeck@latestsimdeck

SimDeck streaming an iPhone simulator inside a development workspace

Run simulators in the background, stream them wherever you work, and give agents stable controls without stealing your screen.

Live simulator where your work already happens

Open Simulator side by side in your favorite IDE or agent orchestrator. Supported in VS Code, Codex, Cursor, Claude Code, and more. Simulators run headlessly in the background for agents to operate on while you stay focused on what matters in the current context.

Pull request previews for mobile apps

GitHub Actions can build the app, boot a simulator, and stream the session back through SimDeck. Review a mobile PR like a web preview: open it, tap around, and merge with actual confidence.

Remote simulator access without the screen-share lag

WebRTC carries the live stream to browsers, teammates, and SimDeck Studio on iOS. Pair once, then drive the simulator from wherever the work is happening.

A CLI your agents can actually trust

Boot, install, launch, tap, type, describe, screenshot, record, and assert. Stable commands and clear JSON errors turn simulators into end-to-end test rigs for every agent in your fleet.

Simulator infrastructure your workflow needed.

Run it headlessly on your Mac, stream it into your editor, or from a PR on GitHub actions. Let agents tap, type, inspect, screenshot, and verify without taking over your desktop.
