How do you build an offline-first app?
Challenge
Apps that rely solely on a cloud database to operate are dependent on the internet. That means internet latency or outages can ruin the user experience.
Solution
Couchbase Capella provides a cloud database, an embeddable database for mobile and IoT devices (Couchbase Lite), and built-in bidirectional data synchronization. Capella makes mobile apps faster and more reliable because local data processing removes dependencies on the internet and distant cloud data centers.

Developing your own data sync is hard
Challenge
Data synchronization is complex. It must be bidirectional, handle conflicts, detect network availability, and retry requests when interrupted.
Solution
There’s no need to develop sync yourself – we’ve done everything for you. Capella App Services provides data sync, authentication, and authorization as an easy-to-use managed backend service for mobile and IoT apps. It includes customizable conflict resolution and precise data routing via filters and channels.

Reusing REST APIs makes apps inefficient
Challenge
When you reuse REST APIs, you send unnecessary data to devices, which wastes bandwidth. Filtering that data on-device erodes performance and battery life.
Solution
Capella App Services includes Couchbase Lite, an embeddable database for mobile, IoT, and custom embedded apps. It lets you store and process data on-device and use SQL to get just the data you need. You eliminate network latency issues and avoid over or under fetching data with inefficient REST calls.

Managing the backend slows development
Challenge
Installing and managing backend servers to handle data processing, security, and synchronization for your app takes time away from development.
Solution
Mobile developers use Capella App Services as an off-the-shelf backend database and sync service for their apps. You don’t have to set up or manage servers. And because it’s fully hosted and managed, Capella eliminates maintenance hassles and allows your development team to concentrate on code.
