Architecture guides and EventCatalog news
Practical guides to documenting distributed systems and the latest EventCatalog features.
Add custom dashboards, tools, and APIs to EventCatalog
EventCatalog now supports custom pages and API routes, so teams can build their own catalog tools, dashboards, workflows, and API-backed pages.
Introducing EventCatalog v4
EventCatalog v4 adds a new vision for our project. New system resource type, context maps, and simpler discovery. EventCatalog CI/CD Agent and faster catalogs. A better community edition, and clearer license models.
Bring live data into EventCatalog
Use custom EventCatalog components to fetch service health, ownership, deployment, and registry data directly into your architecture documentation.
How to turn C4 diagrams into EventCatalog documentation
Two ways to bring C4 architecture modeling into EventCatalog: a Claude skill that converts C4 diagrams (Structurizr, C4-PlantUML, Mermaid C4) into a full event-driven catalog, and the LikeC4 component that renders interactive C4 diagrams directly inside EventCatalog pages.
Whats new in EventCatalog - May 2026
May was one of our biggest months yet. Agents and ADRs are now first-class resources you can document and govern, the EventCatalog Editor is in beta, plus full-content search, GitHub user sync, and more features aimed at coding agents.
Sync users and teams from GitHub into EventCatalog
EventCatalog can now sync users and teams directly from GitHub. Point it at your org, and ownership data stays accurate without manual upkeep.
Your architecture decisions belong next to your architecture
Architecture Decision Records are now a first-class resource in EventCatalog. Document the why behind your design choices and link them directly to the services, events, and domains they affect.
Let tools find your APIs from one URL
EventCatalog can now publish an API catalog at /.well-known/api-catalog, giving agents and developer tools one machine-readable place to discover your service, domain, and MCP API surfaces.
Document and Govern AI Agents in EventCatalog
EventCatalog 3.41.0 adds first-class agent documentation so teams can reduce agent sprawl, track ownership, see model and tool usage, and understand how agents consume and produce information across their architecture.
Edit your EventCatalog without opening Markdown
EventCatalog Editor is now in beta. It gives your team a local visual editor for maintaining catalog resources, previewing changes, reviewing diffs, and publishing local Git commits.
Flows now support containers and data products
EventCatalog v3.36.3 adds two new flow node types, containers and data products, so you can model the full journey from services and events through to data stores and analytical products in a single diagram.
