# OpsMill — Infrahub

> OpsMill builds Infrahub, an open-source, graph-based infrastructure data
> management platform that serves as a unified source of truth for network,
> data center, and cloud automation. It combines an extensible schema, native
> version control (branching, merging, peer review, CI), and unified Git +
> graph-database storage, exposed through GraphQL, REST, a Python SDK, the
> infrahubctl CLI, a web UI, and an MCP server for AI agents.
