# System Initiative

> System Initiative is an AI-native infrastructure automation platform. It builds an interactive digital twin of your cloud infrastructure — modeling resources as components inside reviewable change sets — so teams and AI agents can discover, simulate, and safely apply changes. It works alongside Terraform, Pulumi, and GitOps and exposes a workspace-scoped Public API plus a first-party MCP server.
