Every agent needs a sidekick to hold the phone.

Cloud Xcode, iOS, Android and TV devices your coding agent builds, verifies and submits — on a live device it can see and touch. You watch along in the browser and take over anytime.

From first build to final check.

Build

Cloud Xcode + Gradle without a Mac. Signing handled, TestFlight + Play submit from the terminal.

Preview

One link puts the live app in anyone's browser. Guests watch, take over, embed anywhere.

Test

Record once, replay everywhere. Visual regression + CI checks keep running after the agent leaves.

Your agent gets the controls.

Register Sidekick as an MCP server once. Your agent launches the app, reads the UI tree, taps, types and screenshots — while you watch and take over anytime.

The same loop reaches the living room.

Apple TV and Android TV with d-pad verbs and focus-walk. Roku on real hardware (roadmap). Same verbs: ui-tree, press, tap-focused, screenshot.

Head-to-head comparisons with VibeView, EAS Simulator, BrowserStack, EAS Build, Limrun, Appetize, AWS Device Farm, LambdaTest and Sauce Labs — sourced, dated, explicit about where each one beats us.

Common questions

Do I need a Mac to test an iOS app?

No. The simulator runs on our fleet (or your self-hosted Mac mini). Your machine and your agent's sandbox only need the sidekick CLI.

Are these real phones?

Simulators and emulators, like Appetize and Limrun. Roku runs on real hardware (roadmap). For sensor-grade real-device matrices, BrowserStack remains the answer — we say so on their page.

How is this different from Limrun?

Same high-level interface so migration is trivial — plus TV devices, post-agent testing, Play submission, public pricing, self-hosting, and a source-available license. Full breakdown on the Limrun alternative page.

What does the free tier include?

30 streaming minutes and 10 cloud builds a month, no card. Self-hosting is unlimited and free.
