Revelation EA is a free, browser-based enterprise architecture tool designed for teams establishing an EA function, supporting transformation initiatives, or modeling at the project level. It provides a consistent, lightweight way to capture and visualize architecture using familiar formats like Excel and JSON - accessible to both business and technical users. With a “diagrams-as-code” approach, it supports version control through Git and enables integration with AI tools. Diagrams are generated automatically from structured data and stay in sync as models evolve, helping maintain clarity and consistency across teams and projects.
