A control plane so parallel coding agents stop fighting over the same simulator

Simlock is a CLI-first control plane for iOS simulators and Android emulators, built for environments where multiple coding agents run at the same time — on one machine, or across a fleet of them behind a single address. Agents don’t touch simctl or avdmanager directly — they ask Simlock for a device and get one back, booted and health-checked, that no other agent will touch until they’re done with it.

Why you’d want this

Two agents, one simulator, zero coordination. Left to themselves, agents that need a device grab whatever simctl / avdmanager happens to show them. Two agents that pick the same one start booting, erasing, and installing over each other — without either ever knowing the other exists. Simlock gives them a single primitive instead: lease a device.

You don’t provision devices by hand. If nothing matching is free, Simlock provisions one itself, up to a capacity limit it derives from the machine’s CPU and RAM. Once that limit is reached, further requests block and wait in a fair queue rather than failing outright, with --timeout and --no-wait escape…
