# App Quickstarts

Build durable, distributed applications on [Diagrid Catalyst](https://docs.diagrid.io/operate/hosting/catalyst-cloud). Each app quickstart runs end-to-end in under 15 minutes and is available in your preferred language.

- **Workflow** — run a stateful, multi-step order-processing workflow using the Dapr Workflow SDK. You'll provision a managed workflow engine, chain inventory, payment, and notification activities, and inspect executions in the Catalyst console.
- **Dapr APIs** — call Dapr's distributed application building blocks. These quickstarts cover service invocation, state management, and pub/sub, each runnable per language.
