## Best for

Mobile teams running multiple agents that need their own simulator instead of fighting over one.

## Why it deserves attention

Simlock turns a Mac into a pool of warm iOS simulators and Android devices, then hands them out over a CLI, agent-device helper, or HTTP API so each coding agent gets an isolated lease. Start on one machine, add more Macs and Linux boxes behind a gateway, and agents anywhere use a single URL. It is MIT-licensed, free, actively developed, and already integrates with T3 Code. The project is young, capacity is limited by the machines you own, and setup and device cleanup still need care.
