Why EventCatalog?

Distributed systems and software architecture can become complex and hard to govern.

As domains, systems, services, and messages increase, so does the challenge of understanding, documenting, and communicating what’s happening across the system.

Without proper documentation/context, our systems can become ablack box, leaving teams struggling to keep up.
