Tophat by Shopify

TL;DR

A tool to pull mobile app builds directly from your CI pipeline to a device, skipping the painful local build process.

Who is this actually for?

Mobile engineers and QA teams at mid-to-large companies who spend half their day waiting for Xcode or Gradle to finish compiling.

The Good

• Eliminates the 'it works on my machine' excuse by testing the exact artifact that will eventually ship.
• Major time saver for product managers who need to verify a feature without setting up a full dev environment.

The Catch (Potential Downsides)

Your CI pipeline becomes a single point of failure; if your runners are backed up, this tool is useless. Also, expect some initial friction getting your build artifacts exposed correctly.
