Tophat by Shopify

Tophat is Shopify's answer to a problem every mobile developer knows too well—you've got a CI build ready, but actually testing it on a real device means setting up simulators, provisioning profiles, cable connections, and about an hour of your life you'll never get back. Tophat skips all of that. One click, and your CI build installs and runs on any device in your fleet—whether it's your own phone, a device lab, or a team member's iPhone across the office. No cables, no simulators, no building locally just to test.

It's built by the same team at Shopify who's running one of the largest mobile commerce apps in the world, handling millions of transactions daily. They've open-sourced Tophat because every mobile team wrestles with this same bottleneck and there's no reason everyone should keep reinventing the wheel. It's on GitHub now, free to use, and ready to integrate into your existing CI pipeline. If you're still plugging in devices to test builds in 2025, Tophat just made your workflow obsolete.
