Developer releases Manzanas MCP for orchestrating Codex agents across iOS simulators on multiple Macs
A developer open-sourced Manzanas, an MCP server that lets a Codex orchestrator control seven iOS simulators across three MacBooks in real time. It parallelizes app smoke tests by giving each agent its own simulator instead of one agent running tests serially. The tool targets faster iOS test cycles for practitioners running agent-driven QA.

AI Overview
- Manzanas is an MCP server enabling a Codex orchestrator to control 7 iOS simulators across 3 MacBooks in real time
- Distributes smoke-test load across multiple agents, each armed with its own simulator, instead of one agent running tests for several minutes
- Simulators are slimmed to under 1GB RAM each
- Manzanas MCP claims the fastest action execution on simulators
- Source code available at GitHub repo BariBariGood/Manzanas

iOS Simulator Lease Manager for Coding Agents
A daemon that manages iOS simulators as leases for coding agents, preventing collisions and speeding up agent workflows. It assigns simulators to agents on request, parks idle ones with SIGSTOP to save CPU, and returns warm simulators in ~0.28s instead of a 7s cold boot. Solves the problem of multiple agents fighting over a single simulator, improving reliability and efficiency for developers running parallel coding agents.

Manzanas - runs a dozen iOS simulators on one Mac and leases them to coding agents
Manzanas is a tool that runs many iOS simulators on a single Mac and makes them available to coding agents. LLM-based agents lease simulators to build and test iOS apps autonomously. It solves the scarcity of iOS test environments for teams running multiple AI coding agents.

SimSlim reduces iOS Simulator memory usage by disabling unnecessary services
SimSlim is an open-source tool that reduces the memory footprint of iOS Simulators by disabling background services not needed for testing or development. It uses Claude Code (an LLM) to help build the tool, but the tool itself does not use LLMs at runtime. It solves the problem of high memory usage per simulator instance, enabling developers to run many simulators simultaneously on limited hardware.

Manzanas: simulator fleet letting AI agents drive iOS apps
Manzanas is a Go daemon that spawns a fleet of iOS simulators on one Mac so AI coding agents can actually operate the apps they build. Agents tap through the UI by accessibility label and verify each step with real screenshots. It solves the problem that agents could write iOS code but had no way to drive a real simulator, and works over SSH so agents on Linux or Windows machines can control iOS.

Pingfusi: Human QA testing orchestrated by Claude via MCP
Pingfusi is a turnkey flow that lets Claude file QA tests through MCP, which are then staged to real people on real iPhones. Testers run the tests and leave comments, which come back into Claude's context for fixing, removing the developer from the loop.
