# Developing and shipping Flows custom apps

> Follow Flows custom app guides from first project creation through local development with Vite to deploying React apps inside Cognite Data Fusion (CDF).

Walk through creating a **Flows custom app**, running it locally, and publishing it to CDF in a single guided path. Before you build for customers, review the [quality guidelines](/cdf/flows/guides/quality-guidelines) — they define the standards your app must meet for certification.
