Limrun

Limrun is a San Francisco and Istanbul-based developer-infrastructure startup (Y Combinator, Spring 2026 batch) that puts native mobile development tools - Xcode, iOS simulators and Android emulators - into the cloud so AI coding agents can build, test and preview mobile apps without a Mac on someone's desk. Founded by Muvaffak Onus, the company gives agents running in sandboxes like Replit or CI runners the ability to compile apps, stream build logs, drive simulators and share browser previews, and already powers mobile workflows for Replit, Rork, Momentic and others.
