What is ZenEA?

ZenEA is a open-source solution to manage Enterprise Architectures, with a strong focus on Application Portfolio lifecycle management and rationalization strategies.

You can import data from LeanIX to seamlessly continue with existing inventories – or start capturing your portfolio from scratch in a Git-backed, fully versioned way.

Basic concepts

Every Application is represented as a JSON file on disk, linked to a Git repository and branch:

/data/<gitRepoName>/<gitBranchName>/<EntityType>/<ID>.json

e.g.

/data/myea/master/Application/12c8ba76-27d5-4479-b3bd-7778c60f0665.json

The Manage Branches admin area lets you check out additional branches and start working with them. Changes you make in list and detail views are auto-saved. To capture explicit snapshots, use the Git Commit command and rely on your Git provider for diffing, branching, and merging.

Differentiators

• Free for non-commercial use
• Data fully version controlled via Git
• Snappy, keyboard-friendly editing for mass updates
• MCP endpoint exposed so local LLMs can extract and enrich data
• Minimal runtime dependencies – can even run on basic PHP-enabled webspace
