SMALL DETAILS. LESS FRICTION.

Made for the way
you already work.

LOCATION, SORTED

Test from anywhere.

Drop a pin, search a place, or revisit a saved favorite. Give your location-aware website a change of scenery.

THE REAL NATIVE TOOLS

Inspect. Navigate. Keep going.

Use the full Safari Web Inspector. Inspection stays attached during normal navigation, so you can stay with the problem.

A place for every window.

Tile your tools together. Re-tile when you need to. Restore their previous positions when you stop.

Close the window. Keep the flow.

Your workspace keeps running in the menu bar, with reload, re-tile, and stop always within reach.

WHY DEVICE HELM EXISTS

Building is the interesting part.
Setting up shouldn’t be.

I built Device Helm to stop arranging the same windows and repeating the same steps every time I tested a website on iOS. A small, focused tool to make getting started feel a little more effortless.

A FEW GOOD QUESTIONS

Before you
jump in.

What do I need to run it?

An Apple silicon Mac running macOS 15 or later, Xcode with an installed iOS Simulator runtime, and Safari’s developer features enabled. Device Helm checks your setup and guides you through Accessibility permission on first launch.

Does it work with localhost?

Yes. Start your development server, enter its localhost URL in Device Helm, and open it in simulated Safari. Device Helm does not start the development server for you.

Is this a browser or device emulator?

Device Helm coordinates Apple’s real iOS Simulator and Safari Web Inspector. Their native windows are arranged together. Physical iPhones and iPads are not supported.

Is the beta free?

Yes. The current beta is free, independently distributed, and requires no account or subscription. There is no analytics tracking.

How do I install the beta?

Download the DMG and copy Device Helm to Applications. The beta is not notarized yet; macOS may require you to allow it in System Settings → Privacy & Security before first launch.
