EventCatalog is a tool that helps you write down and organize information about your software system. Instead of just writing generic pages, you can document the different parts of your system like services and messages, and even make diagrams. It also has AI features to help you find information and can work with other tools.
EventCatalog is an open-source documentation platform designed specifically for software architecture. It allows teams to document domains, services, events, commands, and schemas in a structured way, reflecting how they actually build their systems. Key features include a visual architecture explorer, AI-powered natural language querying, a schema explorer supporting OpenAPI, AsyncAPI, Protobuf, JSON Schema, Avro, and more, and the ability to attach custom docs like ADRs and runbooks. It supports semantic versioning, offers 15+ generators for importing from AsyncAPI, OpenAPI, Kafka, Confluent, AWS EventBridge, and more, and is highly customizable with themes and MDX components. Enterprise features include OAuth2, RBAC, schema governance, and breaking change detection. The tool is built with TypeScript and uses a monorepo structure with pnpm and Turborepo.
