Test mobile CI builds on any device without building locally
Mobile devs waste hours building branches locally just to test a PR. Tophat pulls any CI artifact and installs it on simulators or physical devices. For iOS and Android engineers.
Tophat by Shopify is an open-source macOS app that pulls CI build artifacts and installs them directly on simulators or physical iOS and Android devices, no local clone or build required.
It solves the "I have to build this myself just to see if it works" problem that slows down every mobile engineer reviewing someone else's PR. Give the agent a branch name, PR number, or URL and a target device. It finds the right build, installs it via Tophat, and you're testing in seconds. The manual handoff is gone.
Key features:
CI artifact install directly to simulators and physical devices
Claude Code integration for agent-triggered installs
Quick Launch for pinning favourite app builds to the menu bar
tophatctl CLI for scripting and CI pipeline integration
TophatKit SDK for custom artifact providers and build systems
File association support for .ipa, .apk, and .zip
Built for iOS and Android engineers who review PRs regularly and want to cut the build-first tax out of their workflow entirely. If you could hand one more step in your mobile review workflow to an AI agent, what would it be?
