Features Overview
KMPStarterKit ships with a lot of features already wired up. Before building something yourself, scan this page — chances are it is already provided.
The features are grouped into three areas:
- Integrations & Services — app capabilities backed by an external service or SDK.
- App Building Blocks — Kotlin APIs, utilities, and UI you build your app with.
- Build & Release — the test, tooling, and publishing backbone.
