About Limrun
Summary
Limrun provides remote Xcode, iOS, and Android simulators that let cloud-based coding agents build, test, and iterate on mobile apps without running anything locally. It targets mobile development teams and AI agent platforms whose cloud sandboxes lack native tooling like Xcode or Android emulators. The platform replaces the need to check out code locally to validate and merge mobile PRs.
Business model
A free tier plus paid access to remote native development services.
Go-to-market
AI agent platforms and mobile development teams adopt Limrun directly, with a self-serve console and free tier alongside a demo-booking path for larger integrations.

Extend cloud sandboxes with iOS, Android and more
Coding agents in the cloud don't work for majority of teams who require native capabilities; they lack XCode for iOS, Emulator for Android, Unity for game development teams. We are on a mission to cloudify every local development utility so that regardless of where it runs, your agent can compose an ideal set of capabilities on the fly so you don't need to run it on your laptop. Today, we provide remote services such as XCode, iOS & Android simulators to enable coding agents running in any sandbox to be able to build and iterate over mobile apps, too. Replit, Rork, Momentic, Minitap and more agent companies have built mobile development and testing experiences on Limrun platform. Coconote (Quizlet), SorceJobs (W25) and more companies with mobile apps use Limrun with their cloud agents, merging PRs without having to check out the code locally.
