Dev Browser
A Claude Skill to give your agent the ability to use a web browser
Dev Browser is a browser automation skill/plugin that enables an AI agent to control a real browser for verification and testing during development. Its purpose is to close the gap between “code was written” and “the UI actually works,” by letting the agent navigate, interact with pages, and validate behavior in a live environment. A key idea is persistence: the browser can keep pages open so the agent can navigate once and then perform multiple interactions across scripts without losing state each time. ... -

Browser MCP
Browser MCP is a Model Context Provider (MCP) server

serve-sim
The `npx serve` of Apple Simulators
serve-sim is a developer tool for hosting Apple Simulators through a local or network-accessible web interface. It is described as the npx serve equivalent for Apple Simulators, allowing users to preview and control a simulator from a browser. The tool is especially useful for AI coding agents such as Codex, Cursor, and Claude Desktop because they can interact with a simulator through browser-driven workflows. It can run locally, over a LAN, or through a remote Mac with tunneling. The web UI streams the simulator and forwards clicks, enabling browser-based end-to-end testing and debugging. serve-sim is best suited for iOS development, agent testing, remote simulator access, and mobile UI automation workflows. -
