Helios

Helios is a mobile backend as a service providing a server-side platform to manage user accounts, push notifications, and data synchronization for mobile applications. It functions as a REST API framework that automatically generates database tables and standard web service endpoints from defined data models.

The project implements specialized services for the Apple ecosystem, including a Passbook service for managing digital passes and device registration. It also provides an in-app purchase verification service to decode purchase receipts and validate product identifiers through external verification.

Additional capabilities cover push notification management through device token registration and routing. The system also handles server-side synchronization with client-side data stacks and provides tools for building distribution packages and managing newsstand content via cloud storage.
