Expo Launches Expo Simulators, Cloud iOS Simulators and Android Emulators Built for Coding Agents
Coding agents write mobile code faster than any team can review it. 馃檶 Introducing Expo Simulators: cloud simulators built for agents. Your agent runs its change on a cloud simulator or emulator and brings back the recording before it asks for your attention.
Context
Mobile coding agents can now test their own changes on cloud devices and return recordings, so review stops being the bottleneck.
Expo is a widely used platform for building mobile apps with React Native. Its new service gives agents cloud simulators so they can check their own code. The launch post passed 1.9 million views.
Deep dive
Expo posted on November 12 that coding agents write mobile code faster than any team can review it, and introduced Expo Simulators, cloud simulators built for agents. According to the post, an agent runs its change on a cloud simulator or emulator and brings back the recording before it asks for a person's attention.
Expo's press release says the service lets agents reproduce a reported bug, write and test a fix, verify it on iOS simulators and Android emulators, and leave a screen recording, screenshots and logs on the pull request. It says the service works with agents teams already use, including Cursor, Claude Code and Codex, and that iOS simulators can run without a Mac, from Linux, Windows through WSL, or a cloud sandbox. Expo says the product adds no AI model of its own.
The release gives pricing of $0.10 per simulator minute for iOS and Android, with 60 minutes a month included on Starter, Production and Enterprise plans, and says it is available to everyone on paid plans. Expo's documentation still describes a limited access preview with a waitlist, so access may differ by account.
What to expect next
Watch for how quickly teams wire Expo Simulators into continuous integration, and whether recordings on pull requests actually speed up review. Expo said it expects to share details on prompt injection protections by the end of November. Similar agent focused testing services for web and desktop apps are a likely next step across the tooling market. Pricing per simulator minute will decide how many teams run checks on every change.
