Mobilecode

Mobilecode is an open source fork of opencode, the terminal-first AI coding agent, adapted for people building iOS and Android apps. When it detects an iOS or Android project it runs a simulator or emulator preview server and renders the live device inside the app, next to your session , so a founder or mobile engineer can iterate on native code with an AI agent without alt-tabbing between Xcode, Android Studio, and a chat window. Built by Rob Sandhu, the project wires together two existing tools to make this work: on iOS it detects Xcode projects and workspaces, CocoaPods, and Expo apps, then runs serve-sim and embeds the iOS Simulator stream, and on Android it detects Gradle projects and Expo apps, then runs serve-avd and embeds the Android Emulator stream . Sandhu wrote serve-avd himself, and serve-sim comes from Evan Bacon of the Expo team. Everything else opencode does still applies, including the terminal UI, desktop and web clients, any model provider, MCP, plugins, and skills. The launch matters because AI coding agents have largely centered on web and backend workflows, leaving mobile developers to script their own build and preview loops. Mobilecode closes that gap with concrete plumbing: a titlebar run control that builds the native project, installs it on the running simulator or emulator, and launches it, using xcodebuild plus simctl on iOS and gradlew assembleDebug plus adb install on Android , along with an HTTP API for the same actions. It ships under MIT with an install script and a from-source path via bun, and it keeps opencode's existing configuration and credentials so current users can adopt it without reconfiguring their setup.
