Problem
Mobile development teams and AI coding agents often lack access to the physical hardware and operating systems needed to build and test iOS and Android applications. Cloud agents running on Linux VMs cannot natively compile iOS apps without a Mac, and sharing live simulator previews with human reviewers typically requires complex infrastructure and authentication flows that slow down the development loop.
Solution
Limrun provides real-time remote Xcode, iOS, and Android simulators as on-demand cloud services, so cloud agents can build, validate, and share their work through demo videos and live previews. The platform runs macOS for iOS builds and accelerated emulators for Android, all accessible via a CLI that syncs source code and triggers remote builds with sub-second sync times. A control plane manages instance creation and authentication, while per-instance data planes expose dedicated endpoints and MCP servers that let MCP-aware tools interact directly with each simulator. The embedded simulator component streams the live device into any product UI, and anyone with the URL can open the running simulator in a browser without signing in, enabling seamless human review through Slack links, PR comments, or browser panes.
Target Audience
Primary customers are AI agent platforms, mobile development teams, and product teams building cloud-based development tools that need to provide their users with real-time mobile app testing and validation capabilities.
