The cheapest way to build and maintain an iOS App

Applin is a set of backend libraries and boilerplate mobile apps that do Server-Driven UI.

Applin eliminates iOS code. A single backend engineer can use it to make a full-featured mobile app.

• No iOS coding required
• Instant deployment & rollback
• Update frontend and backend together
• Use backend tests to verify UI flows and backend code together
• Tiny download size (1.2MB)
• Low memory & CPU usage, long battery life
• Fast native widgets

Server-Driven UI

Server-Driven UI reduces costs and ships features faster.

Large tech companies use their own internal SDUIs for competitive advantage:

• Airbnb: A Deep Dive into Airbnb’s Server-Driven UI System
• DoorDash: Improving Development Velocity with Generic, Server-Driven UI Components
• Instacart: Building Instacart’s view model API
• Meta: How we built Facebook Lite for every Android phone and network. Video.

Applin levels the playing field, bringing server-driven UIs to companies of all sizes.
