Stream iOS Simulators to a Browser Window

AI Analysis
●●●BangerBig BrainSolve My Problem
Browser-streamed iOS simulators let AI agents use existing browser tools instead of osascript.
Strengths
- •MJPEG + WebSocket capture via simctl io with zero app instrumentation needed
- •Log forwarding built specifically for browser-use MCP tools
- •60 FPS streaming with gesture and keyboard passthrough
Weaknesses
- •macOS + Xcode command line tools required limits platform
- •Narrow audience of iOS devs using AI agents

iOS developers using AI coding agents
Post Description
Agent tools seemingly know how to work with browsers better than with iPhone simulators, so I built this tool to capture the simulator XPC stream and render it in a webpage. This means Claude Code/Codex desktop apps can use their existing browser-use tools to launch the preview, screenshot, and read logs without getting caught in a osascript loop.
