About the Project
Architeezy is a unified model repository for both people and AI agents.
The Problem
In most organizations, each team relies on its own set of tools:
- Business analysts: ARIS, Business Studio
- Architects: Archi, Visual Paradigm, Enterprise Architect
- System analysts: Confluence, XWiki
- Developers: IDEs, DBeaver, PlantUML, Structurizr
- QA engineers: Test IT, Zephyr
- DevOps: NetBox, Terraform
Knowledge transfer typically happens through screenshots and messages:
- A business analyst documents a process → exports it as an image → embeds it in documentation
- An architect creates diagrams based on that documentation → exports images → uploads them to Confluence
- A system analyst writes requirements based on architectural diagrams
- A developer writes code and designs databases based on textual requirements
- DevOps provisions infrastructure based on written requests
With this approach, it becomes difficult to answer even basic questions:
- Which parts of the codebase, APIs, and data models will be affected by a change in this business process step?
- Which systems depend on a reference dataset that is about to be decommissioned?
- Through which applications does customer personal data flow, and who has access to it?
- What infrastructure supports this business process, and how much does it cost?
- Which processes will stop, and how much data will be lost if this server fails?
Over time, the situation gets worse:
- Agile development: architecture and requirements become outdated faster than code reaches production
- Distributed teams and contractors: critical knowledge is often undocumented and lost when people leave
- AI adoption: rapid code generation without architectural grounding makes systems harder to understand and maintain
What’s needed is a solution that provides a unified, consistent view across teams—and makes it usable for transparent and controlled AI-driven workflows.
The Solution
A unified model repository with the power of an enterprise platform:
- Centralized model repository with versioning and access control
- Support for industry-standard notations: ArchiMate, C4, EIP, EPC, VAD, class diagrams, state machines
- Custom notation builder for domain-specific models (e.g., IT infrastructure, conceptual models)
- Multiple representations of models: diagrams, tables, and code
- Alignment with Object Management Group standards
With the usability of modern collaborative tools (like Miro, Figma, draw.io):
- Simple web interface with real-time collaboration
- Document editor similar to Notion
Plus:
- Easy integration with external systems via API
- Support for Model Context Protocol and a built-in AI assistant
