# Xizor > Xizor is the AI-native subscription platform for mobile apps: a native StoreKit 2 payment SDK (Swift + Expo/React Native), server-hosted paywalls authored as web code that go live on save, complete subscription analytics, and a built-in MCP server so AI agents can read every stat and edit every paywall.
