EventCatalog is an open-source project designed to help you discover, explore and document your event-driven architectures. It uses Markdown and custom components to define events and services, and has a visualizer and 3D graphs to aid in understanding how events flow through your architecture. With the ability to generate documentation from third-party systems using plugin architecture, EventCatalog brings transparency to your landscape. It also offers features such as code examples, node graphs, event schemas, event versions, event owners and much more. EventCatalog is free for everyone to use and outputs a static website that can be deployed anywhere. Join the community, and learn from each other and help shape the project today!
