Limrun

Limrun (Limrun, Inc.) is a Y Combinator-backed cloud infrastructure company for mobile development, built so cloud coding agents and Linux CI runners can build, run, and test iOS and Android apps without a Mac. Limrun exposes three composable cloud services behind one REST control plane at api.limrun.com: iOS simulators running on real Macs (streamable in a browser and drivable programmatically through taps, screenshots, accessibility element trees, video recording, and app lifecycle), remote Xcode and Bazel build sandboxes that accept synced sources and run xcodebuild or remote build execution, and accelerated Android emulators reachable over an ADB tunnel by Android Studio, Appium, or scrcpy. Gradle build sandboxes and a managed Asset Storage service for .apk and .app build artifacts round out the platform. Every instance is created through the control plane with an org API key and returns its own per-instance token, data-plane URLs, a signed browser stream URL, and its own Model Context Protocol server, which makes Limrun one of the few providers shipping a per-instance MCP endpoint alongside first-party Agent Skills for coding agents.

Limrun publishes 7 APIs on the APIs.io network, including Analytics API, Android Instances API, Assets API, and 4 more. Tagged areas include Company, Mobile, iOS, Android, and Simulators.

Limrun’s developer surface includes documentation, API reference, getting-started guide, signup flow, developer console, support, CLI, and 25 more developer resources.
