About Viaduct

Viaduct is an innovative C4 modeling tool designed to help software development teams create, maintain, and interact with live architecture diagrams. It allows users to visually define system contexts, containers, components, and code, enriching each element with dynamic documentation, sequence diagrams, and API contracts. The tool uniquely features an MCP (Model-Code Protocol) server, enabling AI coding agents like Cursor or Claude Code to read and understand the architecture, making diagrams actionable. Viaduct ensures that architectural documentation remains current and accessible, solving the common problem of stale diagrams and empowering teams to build and evolve complex systems with clarity.
