Event-driven architectures are becoming more popular, giving us the ability to write decoupled architectures and use messages as away to communicate between domains/teams.
When starting with event-driven architectures you may have a handful of services and messages. As this scales with your team and organization it becomes very hard to manage and govern this.
Over a period of time more events are added to our domain, requirements change, and our architecture scales.
As more domains, services or messages get added to our architecture they can be hard for teams to discover and explore.
Many teams ignore documentation and governance and end up in a sea of complexity (watch the talk here) .
EventCatalog was built to help document your event-driven architectures and help your teams explore and understand events, schemas and much more.

Think of EventCatalog as a website generator that allows you to document your event architectures powered by markdown.
EventCatalog is focused on discovery and documentation and allows you to:
- Document Domains/Services/Messages/Schemas/Code Examples and more...
- Visually shows relationships between upstream/downstream services using your Events
- Allows you to version your documentation and supports changelogs
- Add owners to domains,services and messages so your teams know who owns which parts of your domain
- And much more...
EventCatalog is technology agnostic, which means you can integrate your Catalog with any EDA technology of your choice and any schema formats.
EventCatalog supports a Plugin Architecture which will let you generate documentation from your systems.
