# Settings

> Configure project settings in Unkey including build commands, environment variables, domains, and production branch per app and environment.

The **Settings** tab in your project dashboard configures the [app](/platform/apps/overview) within your project. Each app has its own build, runtime, and advanced settings scoped per environment.

For single-app projects (the default), you manage settings directly from the project dashboard. For multi-app projects, each app has independent configuration.

See [App settings](/platform/apps/settings) for the full reference of configurable options, including:

- [Build settings](/platform/apps/settings#build-settings) (GitHub repository, Dockerfile, root directory, watch paths)
- [Runtime settings](/platform/apps/settings#runtime-settings) (regions, instances, CPU, memory, storage, port, command, health check)
- [Advanced configurations](/platform/apps/settings#advanced-configurations) (environment variables, custom domains, OpenAPI spec, gateway keyspaces)
