Limrun

Limrun gives your agent iOS simulators and Android emulators in the cloud. Ask for a device and it is ready in seconds, with your app pre-installed if you want. From there the agent works the way a tester would: it takes screenshots, reads the accessibility tree, taps, types, scrolls, opens URLs, launches apps and pulls logs. Delete the device when you are done, or let it shut down on its own.

Building apps and anything that touches local files stays with the lim CLI. The server tells the agent where that line is and hands it the step-by-step CLI instructions when needed.
