What it is

The application catalog is the register of every system your organization depends on — the apps you build, the SaaS you buy, and the partner systems you integrate with. It’s the context layer the rest of your architecture hangs off: the boxes in a C4 system-context diagram, the systems a decision is made about, and the things teams actually own.

Context for your diagrams
Applications are the systems in your C4 context views — define each once and reuse it across every diagram.
Connected in the graph
Decisions, diagrams, and standards link to specific applications, so you can trace what any change touches.
Ownership & lifecycle
Record the owning team, internal-vs-external, and lifecycle status for every system in one place.

Bring your application catalog into one place.
