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 answers who owns it, what it costs, when the contract renews, and when it should be retired, and it’s the foundation your architecture diagrams are built on.

The heart of your diagrams

Applications are the systems in your C4 views. Define each one once and reuse it across every diagram.

Ownership & sourcing

Business and technical owners, vendor, and sourcing for every system, so you always know who to call.

Contracts & costs

Licensing, seats, annual cost, cost center, and renewal dates, so renewals never catch you by surprise.

Lifecycle dates

Go-live, vendor end-of-life, end of support, and planned retirement, so you can see risk coming years ahead.

EA assessment

Criticality, TIME classification, hosting, and data classification: the inputs every rationalization decision needs.

Clean, reportable data

Owners, vendors, lifecycle stages, and more come from lists your admins curate, so the data stays consistent.
