Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
Hoverfly
A Model Context Protocol (MCP) server that exposes Hoverfly as a programmable tool for AI assistants like Cursor, Claude, GitHub Copilot, and others supporting MCP. It enables dynamic mocking of third-party APIs to unblock development, automate testing, and simulate unavailable services during integration.
serve-sim
Control and stream a running iOS, iPad, or Apple Watch Simulator with serve-sim — taps, gestures, hardware buttons, rotation, camera injection, and the live preview.
