simvyn – Universal mobile devtool, no SDK required

Summary: simvyn is a local web dashboard and CLI that unifies iOS Simulators, Android Emulators, and real devices for mobile app testing without requiring SDKs. It simplifies tasks like toggling dark mode, spoofing locations, installing builds, and inspecting app data through a single interface.

What it does

simvyn wraps simctl, adb, and devicectl commands into one tool, discovering connected devices and emulators to manage them via a web dashboard or CLI. It enables quick actions such as installing builds, clearing app data, sending test push notifications, and capturing screenshots.

Who it's for

It is designed for mobile developers who need to test apps across multiple devices and configurations efficiently without switching between terminal commands or IDE menus.

Why it matters

simvyn reduces the complexity and time spent on repetitive device management tasks by consolidating them into a single, SDK-free interface compatible with any framework.
