Most organizations don't have an architecture problem. They have an understanding problem. Engineers know how the services fit together. Product knows what the customer wants. Business analysts know the workflows that drive revenue. Those views rarely live in the same place.
EventCatalog is where they meet. Drill down from a domain into the bounded contexts inside it. From a context into the ubiquitous language the team uses. From the language into the services that implement it. And from the services into the events, schemas, and ownership that bring it all to life.
Bring your own documentation and your own diagrams. Document the business workflows that span teams. Show how internal services and external systems work together. One tool, one source of truth, one shared mental model.
Built for collaboration
Architects model the domains. Engineers document the services. Product owners write the workflows. Business analysts contribute the language. Everyone reads from—and writes to—the same catalog.
From the big picture down to the code
Drill down from domains to services—without leaving the catalog
Anyone in the organization can navigate from a high-level business view all the way down to schemas and ownership.
Domains
Start at the business level. See the domains that make up your organization and the teams that own them.
Ubiquitous language
Drill into a domain to see the shared vocabulary—the terms that engineers, product, and business all use.
Services & messages
From language down to the services, events, commands, and queries that implement the model.
Schemas & ownership
And finally into the concrete schemas, dependencies, and people responsible for each piece.
Who benefits
One tool. Three teams. Same source of truth.
Shared understanding only works when everyone reads from the same map. Each role gets a different angle on the same architecture.
Engineering teams
Find services, schemas, and consumers in seconds. Onboard new hires faster. Reason about change without reading every repo.
- Service and schema discovery
- Producer / consumer relationships
- Faster, safer onboarding
Product owners
Understand which services power which features. See dependencies before scoping work. Talk to engineers in the same language.
- Feature → service mapping
- Better impact and effort estimates
- Shared vocabulary with engineering
Business analysts
Document end-to-end workflows alongside the systems that run them. Trace a customer journey through events, services, and external integrations.
- Business workflows in one place
- Internal + external system view
- Process documentation that stays in sync
Use it for
Common scenarios where teams reach for a shared, organization-wide understanding instead of siloed docs.
Domain modeling at scale
Map your domains, sub-domains, and bounded contexts—and tie them to the services and teams that own them.
Cross-team workflows
Document business workflows that span engineering teams, third-party vendors, and external systems in one place.
Onboarding & alignment
Help engineers, PMs, and analysts ramp up by giving them one navigable map of the system—not a wiki scavenger hunt.
