Model external systems in EventCatalog

Whats new in EventCatalog - March 2026
EventCatalog updates for March 2026
Your documentation is a design artifact, not just a wiki page
The EventCatalog Miro App v2 turns your architecture documentation into interactive, collaborative design artifacts — and sends them back when you're done.
Document who consumes your APIs, not just who owns them
The EventCatalog OpenAPI generator now lets you define consumer services with optional route-based filtering, so you can document the full producer-consumer picture directly from your OpenAPI specs.
Trace every field across your schemas and architecture
EventCatalog now indexes every field from every message schema and lets you search, filter, and trace fields across your entire architecture. Scale plan users get Field Intelligence with type conflict detection and interactive traceability graphs.
Describe the workflow, let the agent build the flow
The new flow-wizard skill lets you describe a business workflow in plain language while your AI agent builds the flow and wires it to your existing catalog resources.
Which fields are your consumers actually using?
EventCatalog already shows you which services consume a message. Now it can also show you which specific fields they use.
Document examples with your schemas
Message Usage Examples lets you ship real payload samples alongside your events, commands, and queries so your team never has to guess what an OrderCreated event actually looks like in production.
Your architecture is changing. Do you know about it?
Architecture Change Detection in EventCatalog monitors your event-driven architecture across git branches and notifies your teams the moment a service starts or stops producing or consuming messages.
The right documentation, in the right place
Stop losing documentation in wikis and Confluence pages. Resource-level documentation lets you attach runbooks, ADRs, guides, and more directly to the services, events, and domains they describe.
See your architecture clearly: Major visualizer improvements
The EventCatalog visualizer just got a complete overhaul. Cleaner nodes, smarter layouts, dark mode support, hover highlighting and more.
EventCatalog Slack integration
Stop searching through wikis and Confluence pages. Get architecture answers where your team already works.
