# Packages

The workspace contains 13 packages with explicit ownership and supported import paths.

`apps/web` owns the web experience and production Worker. Shared contracts and implementations live in the packages below. A package boundary does not automatically make a module safe for a browser: follow the [client/server boundary](/docs/architecture/client-server-boundary).
