PlatformWebfreemiumglobal

EventCatalog is an open-source documentation tool built specifically for software architecture, letting teams document domains, services, events, and schemas for event-driven and microservice systems in a format readable by both engineers and AI agents. It's aimed at architects and engineering teams whose distributed systems are hard to understand from code and generic docs tools alone.
