How the pieces fit: your app on the edge, and every capability it needs — data, files, search, sessions, sign-in, checkout, email, AI — one call away on the same key.
Harakumo is an app's whole backend behind one client. Your front end and server deploy to the Harakumo edge; every capability the app needs is a namespace on the same SDK or a path on the same API, already wired together. The diagram shows a real shape — an online store, end to end — with the role each service plays.
Your server holds the API key; browsers get only what your server hands them (signed upload and download URLs, checkout links) or the auth pool's publishable client id.
