# FAQs

### What is Digia?

Digia is a frontend orchestration platform for mobile apps. It enables teams to create, manage, and release UI and logic from a centralized dashboard—without needing to rebuild or redeploy the app through app stores.

***

### How is Digia different from React Native or Flutter?

Digia is not a UI framework like React Native or Flutter. Instead, it sits on top of native or cross-platform apps (like Flutter) and powers them using Server-Driven UI (SDUI).

With Digia, teams define screens, flows, and logic on a backend dashboard, which are rendered instantly on the app.

***

### Can Digia work with our existing React Native, Native, or Flutter app?

Yes. Digia supports brownfield integration—you can embed Digia-powered flows alongside existing native or Flutter screens.

React Native support is available in beta.

***

### How does Digia impact performance?

Digia is built for high-performance mobile experiences. It uses lazy loading, optimized rendering engines, and micro-optimizations to consistently deliver 60FPS performance, even on low-end devices.

***

### Does Digia support offline use cases?

Digia is optimized for internet-driven apps, where screens and data are fetched dynamically. While it does not support fully offline-first apps, it enables:

* Input-based screens to work offline (if data is passed in locally)
* Offline-first screen caching, allowing users to interact with previously loaded screens
* Proactive caching of selected flows

However, we recommend against building completely offline-first apps with Digia.

***

### How do I create and update screens using Digia?

Digia provides a visual builder where designers and developers can:

* Compose UI using prebuilt or custom components
* Configure business logic and API integrations
* Preview updates in real-time
* Version and release changes instantly

***

### What happens if Digia’s backend goes down?

Digia includes local caching and default screen configurations within the SDK. If the backend becomes unavailable:

* The app continues to function using cached data
* Users experience no visible downtime
* New updates won’t be delivered until backend service is restored

***

### How does Digia handle analytics and events?

Digia integrates with tools like:

* Mixpanel
* Clevertap
* Firebase
* LaunchDarkly

It also supports:

* Custom event tagging
* Funnel tracking
* UI event configuration directly from the dashboard
* Clickstream callbacks for integration with any external analytics system

All analytics are version-controlled and managed server-side.

***

### What’s the developer experience like?

Developers benefit from:

* Sandbox preview and testing environments
* Version-controlled screen definitions
* Real-device testing via SDK or companion app
* Autocomplete and two-way data mapping
* Runtime safeguards and compile-time validation
* Robust debugging tools and expression engine

This ensures fast development cycles and fewer runtime issues.

***

### Can Digia support high-concurrency events like flash sales?

Yes. Digia is designed for scale. It has successfully handled flows with over **10 million concurrent users**, including performance-intensive and time-sensitive workloads.

***

### How do releases work in Digia?

With Digia, releasing updates involves:

1. Designing or modifying screens, components, and logic
2. Promoting changes to a **staging** environment for testing
3. Releasing to **production** through a **staggered rollout**

All updates are delivered via Server-Driven UI—no app store resubmissions required.

***

### Can we customize Digia’s component library?

Yes. Digia supports:

* Custom components and reusable blocks
* Design tokens and theming
* Atomic components to build scalable design systems
* Native component injection via the SDK’s component registry

This allows full alignment with your brand and extensibility for advanced use cases.

***

### What platforms does Digia support?

* **Currently supported**: Flutter, React Native (beta), Native Android, and iOS
